The argument of `(1-sintheta) + i costheta` is

Evaluate : (( 1 + sintheta ) ( 1 - sintheta )) / ( ( costheta ) ( - costheta ) )

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

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

((1+sintheta+i costheta)/(1+sintheta-i costheta))^n is equal to

((1+sintheta+i costheta)/(1+sintheta-i costheta))^n is equal to

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

Show that : Costheta /( 1 - Sintheta ) + Costheta /( 1 + Sintheta ) = 2/Costheta

If sintheta - costheta = 1 , then prove that sintheta + costheta =+-1

If sintheta-costheta=1 ,then find sintheta.costheta

If costheta[(costheata, sintheta), (-sintheta, costheta)]+sintheta[(x, -costheta), (costheta, x)]=I_(2) . Find x.
