If 'θ' is an angle less than 120^°, what is the value of 'θ' if it satisfies the equation 3cos²θ = 2 + sin²θ.

If (sinx + siny) = a and (cosx + cosy) = b, then find the value of (sinx siny + cosx cosy).

[A] (a²+b²-2)/ 2

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

If tan θ + cot θ = 5, find the value of tan²θ + cot²θ.

Simplify (cos13°+sin 13°) /(cos13°-sin13°)

If α means +, β means -, ɣ  means x, θ means ÷ then 30 θ 10ɣ 5α 10β20 is

If tanθ – cotθ = a and cosθ + sinθ = b, then (b² –1)(a² + 4) = ?

If θ is a positive acute angle and cos² θ + cos⁴θ = 1, then the value of tan²θ + tan⁴θ is?
