`1-sintheta+costheta=3/7`

if sintheta+costheta=3/2 then find sintheta.costheta

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

If sintheta+costheta=(7)/(5) , find sintheta.costheta .

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

If A=[[costheta, sintheta], [-sintheta, costheta]] , then |A^(-1)|=

costheta[[costheta, sintheta], [-sintheta, costheta]]+sintheta[[sintheta, -costheta], [costheta, sintheta]]=

If, 5cot theta =3 ,Find the value of (6sintheta-3costheta)/(7sintheta+3costheta)

Prove that : (sintheta-costheta)/(sintheta+costheta)+(sintheta+costheta)/(sintheta-costheta)=(2)/(2sin^(2)theta-1)

If (1+ sintheta-costheta)/(1+ sintheta + costheta)+(1+sintheta+costheta)/(1+sintheta-costheta)= 4 , then which of the following values will be suitable for theta ?
