`(sintheta)/(1+costheta)` is equal to `(1+costheta)/(sintheta)` (b) `(1-costheta)/(costheta)` (c) `(1-costheta)/(sintheta)` (d) `(1-sintheta)/(costheta)`

Simplify (1-costheta)/sintheta

Simplify (1-costheta)/sintheta

(1-costheta)/(sintheta)+(sintheta)/(1-costheta) =___________.

((1-sintheta+costheta)^(2))/((1+costheta)(1-sintheta))=?

(sintheta)/(1+costheta) + (1+costheta)/(sintheta) = 2 cosec theta

prove that- (sintheta+1-costheta)/(costheta-1+sintheta)=(1+sintheta)/costheta

If alpha, beta are roots of x^2 sintheta-(costhetasintheta+1)x+xcostheta=0 where alphaltbeta and thetaepsilon(0,pi//4) then value of sum_(n=0)^oo(alpha^n +((-1)^n)/beta^n) (A) (1-costheta)/(sintheta)+(1-sintheta)/(costheta) (B) 1/(1+costheta)+1/(1-sintheta) (C) 1/(1-costheta)+1/(1-sintheta) (D) 1/(1-costheta)-1/(1+sintheta)

Evaluate costheta/(1+sintheta)

Prove that : (1+sintheta)/(costheta)+(costheta)/(1+sintheta)=2sectheta

The value of (sintheta)/(1+costheta)+(sintheta)/(1-costheta) is :
