If 2sin²θ–5sinθcosθ+7cos²θ=1then possible values of tan θ are

The greatest value of θθ is:

If tan⁴θ + tan²θ = 1, then the value of cos⁴θ + cos²θ is

If cos θ = , then tan θ is equal to.

If 5cosθ – 12sinθ=0 then value of

If sinθ – cosθ = 7/13 and 0⁰ < θ < 90⁰ , then the value of sinθ + cosθ is :

If 3 sin x + 5cosx = 5 then what is the value of (3cosx - 5sinx)
