Math, asked by Nandhu101, 1 year ago

prove that :

cos∅ -sin∅+1/cos∅+sin∅-1 = cos∅+sin∅

adithya02: I think the question is wrong coz no matter what you try, it ends up as cotTheta + cosecTheta

Apxex: I thin is not that our NCERT question WHERE COSECQ +COTQ they ask

done just clicking picture.

identity
1=Sin^2Q +Cos^2Q

Apxex: one guy posted the answer by dividing it by sinQ but his handwriting is not clean

Nandhu101: forward that to me

Apxex: wait

adithya02: I took a different rationalising factor but ended up at 1+costheta /sin theta, same as yours LOL

Nandhu101: haha

Apxex: hey check the answer again I posted his solution

adithya02: I suck at this

adithya02: Yeah actually.. If you divide it by sinTheta and then use the identity cosec²theta-cot²theta=1 then probably you'll get the answer...

adithya02: WTF.. I again arrived at 1+cosTheta / sinTheta when I tried this method

Nandhu101: haha

Answered by adithya02

The answer is always cotTheta + cosecTheta ....
