2 (sin (power 6) theta + cos (power 6) theta) - 3 (sin (power 4) theta + cos (power 4) theta) + 1 = 0
(cosec theta - sin theta) (sec theta - cos theta) = sin theta . cos theta
If sinA = 3/4, calculate cosA and tanA
Evaluate cos2 30Â° + sin2 45Â° - 1/3 tan2 60Â°
If angle A = angle B =45Â°, verify that sin (A + B) = sin A cos B
If cos(A - B) = cos A cos B + sin A sin B, find the value of
