If 4 sin⁻¹(x) + cos⁻¹(x) = π, then x is equal to:
If tan⁻¹(x) + tan⁻¹(3) = tan⁻¹(8), then the value of x is equal to:
If (sin x − cos 60°)/(cos 150° − sin 270°) = 0 and 90° < x < 270°, then x equals:
The number of positive values of x less than 360° which satisfy the equation sin(x/2) = cos x is:
cos⁻¹(1/2) + 2sin⁻¹(1/2) =
sin x × cos 7π/4 × sec 135° × tan 2π/3 × sin 330° = √3/2, then x equals:
tan(sin⁻¹(−3/5)) is equal to:
sin(cos⁻¹(θ) + sin⁻¹(θ)) =
If 4sin²θ = 1, then the values of θ are:
If sin θ + cos θ = √2 and θ is acute, then θ is:
f tan 45° = sin θ, then θ is equal to: (a) (b) (c) (d)
sin⁻¹(x) + cos⁻¹(x) is equal to:
tan(cot⁻¹(x)) is equal to:
