Assertion (A) : cos⁻¹(cos 13π/6) is equal to π/6. Reason (R) : The range of the principal value branch of the function y = cos⁻¹ x is [0, π].
Evaluate : cos⁻¹[cos(-7π/3)]
Assertion (A) : cos⁻¹(cos(13π/6)) is equal to π/6. Reason (R) : The range of the principal value branch of the function y = cos⁻¹ x is [0, π].
Express tan⁻¹(cos x / (1 – sin x)), where –π/2 < x < π/2 in the simplest form.
Simplify : cos⁻¹x + cos⁻¹[x/2 + √(3 – 3x²)/2]; 1/2 ≤ x ≤ 1
If tan⁻¹ x = 3y, then
