WebbWrite down the interval for the principal-value branch of the function and draw its graph: sec - 1 x. Solution. Solve with us. Step 1. Let y = sec - 1 x. ⇒ sec y = sec ( sec - 1 x) ⇒ sec y = x. To make a trigonometric function invertible we restrict its domain which becomes the range of the inverse of that trigonometric function. WebbInverse Trigonometric Functions Problems. Example 1: Find the value of x, for sin (x) = 2. Solution: Given: sin x = 2. x =sin -1 (2), which is not possible. Hence, there is no value of x for which sin x = 2; since the domain of sin -1 x is -1 to 1 for the values of x. Example 2: Find the value of sin-1(sin (π/6)). Solution:
WebbLet us understand the Principal value of Inverse Trigonometric Functions. A principal value of the inverse trigonometric function at given feasible input x will satisfy the trigonometric function at x and that value of x exists in a range of the principal branch.
