Evaluate for `theta` :

`b^2 ( Sintheta - Costheta )^2 = ( a^2 ( b^2 - 1 )^2 )/4`

Evaluate : ( Sintheta - Costheta )^2 + ( Sintheta + Costheta )^2 = ?

Evaluate : ( 1 + sintheta + costheta )^2 =

Evaluate : ( Cos^2theta - Sin^2theta ) / ( ( Costheta - Sintheta )^2

Evaluate : ( Cos^2theta - Sin^2theta ) / ( ( Costheta - Sintheta )^2

Evaluate (1-costheta)^2+(sintheta)^2

Evaluate (1-costheta)^2+(sintheta)^2

If x = a(sintheta + costheta) and y = b (sintheta- costheta) then (x^2 //a^2 ) + (y^2 //b^2) =? (a)3 (b)1 (c)4 (d)2

A value of theta satifying 4costheta sintheta - 2sintheta =0 is

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

If a costheta + b sintheta=3 and a sintheta - b costheta=4 , then a^(2)+b^(2) has the value 25
