If cos θ + sec θ = √5, then the value of cos³ θ+ sec³ θ is:

sin² 7 ° + sin² 8 ° + sin² 9 ° + sin² 10 ° + ……… + sin² 83 ° = ?

What is the simplified value of the given expression?

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

Solve for x in the interval [0, 2π]: 2 sin²x + 3 sinx - 2 = 0.

Find the value of the following:sin(36° + A) × cos(54° – A) + cos(36° + A) × sin(54°–A)

If sin(3θ) = cos(2θ), then find the value of θ between 0 and 90 degrees.

Evaluate the following:

sin 25° × cos 65° + sin 65° × cos 25°

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

If 2ycosθ = x sinθ and 2xsecθ – ycosecθ = 3, then x ² + 4y ² = ?
