The minimum value of 9 cos2 θ + 36 sec2 θ isÂ
If x = r sin A cos B, y = r sin A sin B and z = r cos A, then find x² + y² + z².

If sinθ = 5/13 for an acute angle θ, find:
(a) cosθ, (b) tan(90° − θ).
If sec 4A = cosec (3A - 50°), where 4A and 3A are acute angles, find the value of A + 75.
Find the maximum value of 18 sin A + 7 cos A.

If cot A = √3, then what will be the value of sin4 A?
