Question

cos tetha by 1 minus sin tetha is equal to
1 plus sin tetha by cos tetha.Prove using trigonometric identities

Answer 1

the question is not clear u can add the pic of the wuestions

Answer 2

Hii friend,

Cos theta /1 - Sin theta = 1+Sin theta/Cos theta.

We have:

LHS = Cos theta/1-Sin theta

Rationalizing denominator

Cos theta/1-Sin theta × 1+Sin theta/1+Sin theta

Cos theta (1+Sin theta)/(1-Sin² theta)

Cos theta (1+Sin theta)/Cos² theta

(1+Sin theta)/Cos theta = RHS.


Hence,

LHS = RHS..... PROVED.....



HOPE IT WILL HELP YOU....... :-)
