If for the matrix A=[(costheta, 2sintheta),(sintheta,costheta)],A^(-1)=A^(T) then number of possible value(s) of theta in [0, 2pi] is :

Simplify costheta[[costheta, sin theta],[-sintheta, costheta]]+sintheta[[sintheta, -costheta],[costheta, sintheta]]

The inverse of the matrix [[costheta, -sintheta, 0], [sintheta, costheta, 0], [0, 0, 1]] is
