hello sir images are not screenreader friendly it cant read the images so plz for us dont upload images sir plz i hope you all understand thank you

U ri8 bro…but trigonometry question format is much different & difficult to typing….that y mam pôster to upload imagens……in trigonometry degrees terás r dere…

Thats y trigonometry quizes are rare in s.a……

ssc cgl syllabus has changed . can't believe

Bro any oficial information from ssc

b b d c d a c b _ a

Frnds thr is no information on official web abt sylbss

8. A

Plzzz send complete solution of 8th ques

Meri Ayushi mam??

DM we did not find any such link on official site. As soon we get some official update, we will update it on SA!

Oye wo meri ayushi maam hai 😀

Hi Sam. How was your exam?

forgot everything:/

Yes…if Ssc syllabus hás changed,,,mam posted about syllabus for us…dont worry…

Han to ..m her favorite..

7-c

Where?

sorry for this

Yes ma'am notifications are so closer it's better to confirm it soon for preparing btw what topics may change ma'am??

9-c?

Hello mam,exam.was OK mam did only 97 out of 160 ..its nt as per my expectations ..nd did all of the 3 descriptive…

Mujhse zyada favorite nahi ho tum 😀

Why?

Leave …jo b hai…I don't want arguments…

1-(b), 2-(b), 3-(d), 4-(c), 5-(d), 6-(a), 7-(c), 8-(a), 9-(b), 10-(c).

studied all those formulas in school:/ nw dnt remember

If exam goes to on-line mode, then you can expect a huge change in reasoning section. For that to happen, we need to wait for the official notification to come!

OK!

Refresh!

What about GA section will it be same??

I need ur help mam..for my prep in a.way .I have nicl assistant on 26 dis month …nd at any how I wanna crack.it…u will guide me na mam??

Sams hwz ur exam ?

Hehehe 😛 me too forget that's why I request ma'am to post something regarding Trigonometry

Ok

hm:)

Bs doob Marne ki situation h yr…aaj jyada question ne attempt kr pae twinks..

Yes sure dear. Practice is the key to succeed in Reasoning and Maths Section. For gk, have a look at the capsule and Hindu Review of past three months. Read newspaper for English section.

Also solve daily quizzes on BA and SA. I am sure it will help you!

2.75/4 tataa

Most probably yes!

Hmm 🙂

# means plus

cos (A#B)#cos (A-B)—2cosAcosB

cOs (180-@)– -cos@

Cos (60-8) #cos (60#8) # cos (180-8)—

2cos60cos8-cos8

Cos8*(2*cos60-1)–0

Hey solve remaining also

dnt knw…c u ltr..

are aisa mat bolo..dont wry fci mast hoga…

Mam I am doing…bs I need maximum.revision which is actually a mool.mantra for successs…the only thing.is to avoid negative marking…iski wajah se I already loose my important exams ..now I know my weak.as.well.as.strong point …I will definitely work for thus mam nd from.today I have 22 more days to work on ..so I will increase my.performance…

Han bs inhi sb cheezo se seekh mil.jaye or.kya chahaiye…ab bs acha acha Karna hai dear

Exam mujhe kuch questions tough lagey..baaki tm.kr logi

Yes…exam.was nt good..don't ask for exam.plz…

m apply ni ki thi nicl..2015 exams fci se start

mam plz check ANS of Q10 it should be A not C

I m also agree vd uuu

Dont mind about exam…k….hás ur lunch

hmm

infinity has no limited value….

Q10

sol… A+B=180.. B=180-A

(Sin)^2 A -(Sin)^2 B =(Sin)^2 A +(Sin)^2(180-A)

=(Sin)^2 A +(Sin)^2 A = 2*(Sin)^2 A

Hello mam I m preparing for SSC cgl can u plz guide me for how I can improve language portion

hmm..tq 🙂

Mine also on 26th…..do work hard…iam sure u will crack it….all d best….dont think on todays exam….

Hmm…correct

Mam r u thr???

thanks for posting trigo questions as many of cgl aspirants find this topic very difficult and pls take trigo and algebra quizzes regularly

Hi Ankit, for English section, read newspaper daily. Also refer to book "Perfect Competitive English" by V K Sinha. I am sure this will help you in improving English.

how to master in trigo and algebra any advice?

It will help : –

A + B = 180

sin^2 A + sin^2B = sin^2(A +B) = sin^2 180

= sin(90 + 90)^2 = (cos90)^2 = 0

i don't have any idea bro…. b/c i also want to b master in trigo & algebra…..

i think u shd ask frm Ayushi mam…. she will guide u….

Thankuuu mam

From now iam a silent reader in s.a …only participate in quizes……waiting for after 12 th quizes…..sure i will participte….k all d best.

Plz explain 8 and 10

All the best to u too…by by

sin^2 A + sin^2B = sin^2(A +B)

how will it come bro…..

plz don't like this in exam….

K.ser u in monday quizees

ldc ke descriptive test ke bare me pata chala kaya

1st learn basics in trigonometry,,,,then practice practice practice,,,,iam sure u will be master in trigonometry..all d best

Q8..

Cos 52 + Cos 68 +Cos 172

apply formula Cos C + Cos D

=2Cos(C+D/2)*Cos(C-D/2)

Cos 52 + Cos 68 +Cos 172=

2Cos(52+68/2)*Cos(68-52/2) +Cos(180-8)

=2*Cos 60 * Cos 8 +(-Cos 8)

=2*1/2 * Cos 8 -Cos 8

=Cos 8 -Cos 8 = 0

scroll down i have expl Q 10

thanx… sam

gd nyt and tc…

ok

Gd nyt shadow tk cr..study well..

Ohhhkkkkyyyy thanks yrrr

yes actually I don't chat generally ..ppl make fun some times …

Leave that faltu typo people na…u can participate in quiz to gain knowledge…

english kaise thi po Jaise ya clerk jaise

shadow please help to solve this

this one

Nt tough than PO bt nt easy as clerk

yes will try ..u r from ?

M from.Delhi…

ok great….:-)

let (p/a) be A , (q/b) be B , (r/c) be C then the two equations are A+B+C = 1 and 1/A+1/B+1/C=0; which on simplification gives AB+BC+CA=0

Now on squaring equation 1 from both sides;

A^2+B^@+C^@+2AB+2BC+2CA = 1

A^2+B^2+C^2+0 = 1

(p/a)^2+(q/b)^2+(r/c)^2 = 1

ans is C

Anyone explain q no 6… 🙂

can you pls explain 6 and 10

Hello shadow exam nt so bad nt so good i ll clr all section bt nt sure abt overall marks attempted 110 discreptive was also good

Nd sry for late rply i reached home at 7:30 pm and was tired

Me too will clear sectional but a huge doubt in overall…

Rinku ji.. i don't use multimedia phone… that's y i hv attached image formed by paint …u can assume any quadrilateral such as square, rectangle, rhombus etc u will find same ans

let in Quadrilateral AB =a, BC=b, CD=c, DA=d

and in quadrilateral EFGH

since E is mid point of OA and

H ismid point of OH

then EH=AB/2=d/2

similarily EF=a/2

FG=b/2, GH=c/2

parimeter of quaABCD=(a+b+c+d)

parimeter of quaEFGH=(a+b+c+d)/2

required ratio =par EFGH/parABC

=1:2

if ans correct pzl replyplz explain Q. 5

Shadow But Ans should be (A) 1:4

simple hai

sin(90-20) + cos(90-50)/cos 20 + sin 50

or cos20 +sin50/ cos 20 +sin 50 =1

Ans c

Guys, Is inverse trigonometry in the ssc cgl both in tiers? Please confirm me..

plz explain q 10

i want to attempt for ssc cgl 2015 please suggest books for preparation thank you

Kiran publications please.. r s a Garway for verbal and non verbal.. English for Arihant

ans for 10 is (a) i think because sin(180-A )lies i the second quadrant where sin is +ve… kindly correct me if i m wrong

Plz tell me hw to tackle with the maths sections its literally headache for me

Practice Kiran publications

Smbdy plz xpln 6&10

Thanks

Bcz of local lang i got only 8 in intrvw in ibps clrk and missed overall cutoff by 2 marks

now i hav naicl intrvw on 13th april…

Here also local lang prob(i knw only read and write)

any solution???

Plz explain 5th one…

Q5..

(Sin 70 + Cos 40)/(Cos 20 +Sin 50)

=(Sin(90-20)+Cos 40)/(Cos 20 +Sin(90-40))

=(Cos 20 +Cos 40)/(Cos 20+ Cos 40)

=1

please explain 5

Q5..

(Sin 70 + Cos 40)/(Cos 20 +Sin 50)

=(Sin(90-20)+Cos 40)/(Cos 20 +Sin(90-40))

=(Cos 20 +Cos 40)/(Cos 20+ Cos 40)

=1

thnx..

answer is right thanks you

thank you !

A+B=180 => B=180-A

now we can write,

sin^2 B= (sin(180-A))^2=Sin^2 A

then,

Sin^2 A +Sin^2 B=Sin^2 A + Sin^2 A =2*Sin^2 A

Q.6

let y=(cos x+ sin x),then derivative it with respect to x,i.e.

dy/dx = -sin x + cos x

now for maximum value put dy/dx=0

i.e. -sin x +cos x =0

i.e. cos x = sin x

i.e. x=45

now ,sin x+cos x =2*sin x

=2*sin 45=2*(1/sqrt 2)=sqrt 2

*** it is actually a lengthy process.i compress it by step jump.

Q.6

you can put the options in the equation,since option (c) & (d) are not lie in 0 to 90. so just check for (a) & (b)..

otherwise,

sin^2 x – 2*cos x+1/4

= (1- cos^2 x)-2*cos x+1/4

=5/4-(cos^2 x+2*cos x)

=9/4-(cos^2 x+2*cos x+1)

=(3/2)^2-(cos x+1)^2

=(5/2+cos x)(1/2-cos x)

either, or,

5/2+cos x=0 1/2-cos x=0

cos x=-5/2 cos x=1/2

x= 60 degree.

2nd method….

(SinX +CosX)

=srt(2)[(1/srt2)*SinX +(1/srt2)*CosX ]

=srt(2)*Sin(X+pie/4)

as we know maximum value of SinX is 1

so max value of Sin(X+pie/4) will also be 1

(SinX +CosX) = srt(2)*1

= srt(2)

yeah if we find two or more value of X then we have to differentiate again… its very lengthy process

Hey frnz any idea ssc ldc ka result kab declare hoga nd ibps v ka preliminary syllbus ka kuch idea..

But ans given is c…

cos20 + sin50/cos20 + sin50 = 1 how????

sin70 can be written as Sin (90-20)and Cos 40 as cos(90-50)so they are equal to COS 20 and Sin50

thank you…

Miss yamuna …

Please remember

-√2<= sinA + cosA =< √2

You can do this by approximation …. 😂

ok i got it… actuly i thought que is Sin70 +(cos40/ cos 20) +sin 50….. jbki que tha (sin70+ Cos 40)/( cos 20 +sin 50)… thats y mujhe samjh hi nhi aya… but thankyu Hemant ji

Gd mrng ayushiii mam ….. Plz post some geometry ques today

thank u so much

is there any necessary to take coaching for ssc cgl ?

No need sir.. study hard. It's pay you
