The maximum value of 15 sin2 θ + 8 cos2 θ is
If x - √(3y) =19 Then find the slope in angle?
If 2y . cos θ - x . sin θ = 0 and 2x . sec θ - y . cosec θ = 3, what is the value of x² + 4y²?
If sinθ +cos θ = √5/2, then find the value of sinθ – cosθ.
If tan A = 1 and tan B = √ 3, what is the value of cos A . cos B - sin A . sin B?
If SecA + TanA = 2√2 + 3, then find the value of Sin A + Cos A
