Which part of the Indian Constitution deals with

tan 20˚ x tan 23˚ x tan 67˚ x tan 70˚ = ?

If tan α = 1/2, tan β = 1/3, then find α + β.

What is the simplified value of the given expression?

2(sin² 15° + sin² 75°) + 4sin 30° - (2sec 60° + cot 45°)

If sec a + tan a = 3, find the value of sin a. 

If  tan 12θ x tan 6θ = 1 then the value of tan 9θ is

If sec²x + csc²x = 10, find the value of tan²x + cot²x.

If √3 tan 2θ – 3 = 0, then find the value of tanθ secθ – cosθ where 0 < θ < 90°

Find the value of the given trigonometric expression:

(sin 25°cos 65° + cos²25°) × sin 30° + (cos 60°tan 45°) × sec 60°

If sin α + cos β = 2 (0˚ ≤ β < α ≤ 90˚), then sin[(2α + β)/3] =?
