If `costheta+sqrt3sintheta=2`, then `theta=`

If costheta+sqrt(3)sintheta=2, then theta= a. pi//3 b. 2pi//3 c. 4pi//3 d. 5pi//3

sqrt(3)costheta+sintheta=2 then theta =

If sintheta+costheta=sqrt(2)sintheta , then sintheta-costheta=?

If 3costheta=5sintheta , then ((5sintheta-2sec^(3)theta+2costheta)/(5sintheta+2sec^(3)theta-2costheta))=?

If r costheta = 2sqrt3, r sintheta = 2 and 0^@ < theta < 90^@ , then the value of r and theta are

If P={theta:sintheta-costheta=sqrt2costheta} and Q={theta: sintheta+costheta=sqrt2 sintheta} , then show that P = Q.

If : cos theta-sintheta=sqrt2.sin theta, "then": costheta+sintheta=

If sqrt3costheta=sintheta , then the value of (4sin^(2)theta-5costheta)/(3costheta+1) is:

If sqrt(3)costheta+sintheta=2 , then general value of theta is:

If costheta-sintheta=sqrt(2)sintheta , then prove that: costheta+sintheta=sqrt(2)costheta
