(1 + tan²A) + (1+ 1 /tan²A)

[A] 1/ (sin²A-sin⁴ A)

[C] 1/ (cos² A-sin⁴ A)

The maximum value of 45 sin θ + 28 cos θ is:

If tan θ = 8/3 , then the value of (3Sinθ+2 Cosθ )/(3 Sinθ-2Cosθ) is

If 9 sinx + 40 cosx = 41 then find tanx.

If A and B are complementary angles, then the value of-

sin A cos B + cos A sin B – tan A tan B + sec ²

If x = r sin A cos B, y = r sin A sin B and z = r cos A, then find x² + y² + z².

(cos5°+sin5°)/(cos5°-sin5°) is equal to:
