If `3cottheta=1`, then find the value of `(3costheta-4sintheta)/(5sintheta+4costheta)`.

If costheta:sintheta=1:2 , then find the value of (8costheta-2sintheta)/(4costheta+2sintheta)

(sintheta+sin2theta)/(1+costheta+cos2theta)

Solve sqrt(3)costheta-3sintheta=4sin2thetacos3thetadot

If sintheta=x and sectheta=y then find the value of cottheta

costheta -sintheta -cottheta +1=0

Prove that [{:(costheta,-sintheta),(sintheta,costheta):}] is orthogonal.

(cosectheta)/(costheta)-(costheta)/(sintheta)=?

If sin theta = 4/5 , then find costheta

(costheta + isintheta)^4/(sintheta + icostheta)^5 is equal to.
