The angle of depression of two ships from the

Find the value of the given trigonometric expression:

(sin 15°cos 75° + cos²15°) × sin 30° + (cos 60°tan 45°) × sec 60°

If secθ + tanθ = 5/2 for an acute angle θ, find sinθ.

If cos2B = sin(1.5B + 48^o), then find the measure of 'B'.

If 6sin²x + 2cos²x − 3 = 0, then find the value of sinx, given that 0° < x < 90°.

Find the value of sin(θ) if 2sinθ = tanθ, for 0 < θ < 90°.

If tan² 45°- cos² 60° x sin 45° cos 45° cot 30°, then find the value of 'x'.

If (sinθ+cosθ)/(sinθ-cosθ) = 2, then the value of sin⁴ θ is

The minimum value of 9 cos² θ + 36 sec² θ is 

Solve the following trigonometric expression:
