Question 20: Find the values of sin(π/3 -sin (-1/2)) is equal to (A) 1/2 (B) 1/3 (C) 1/4 (D) 1

Class 12 - Math - Inverse Trigonometric Functions

Answer 1

As sinx is an odd function therefore sin(-x) is equal to - sinx.

Using above, the equation becomes,
Sin(pi/3+pi/6) = sin(3pi/6) = sin(pi/2) = 1

Hope you get your answer.
