Find value of k if sin⁻¹[k tan(2 cos⁻¹(√3/2))] = π/3.
If a = sin⁻¹(√2/2) + cos⁻¹(-1/2) and b = tan⁻¹(√3) - cot⁻¹(-1/√3), then find the value of a + b.
Evaluate : sin⁻¹(sin(13π/6)) + cos⁻¹(cos(π/3)) + tan⁻¹(√3)
Express tan⁻¹(cos x / (1 – sin x)), where –π/2 < x < π/2 in the simplest form.
Find the value of tan⁻¹(tan 3π/5) + cos⁻¹(cos 13π/6) + sin⁻¹(–1/2).
