### Question

**If sin x=0 then x = __**

A. (2n+1)π/2

B. (n+1)π

C. nπ

D. nπ/2

**Answer:** C

**Solution:**

When know, sin x = 0 whenever x is 0, π, 2π, 3π,…. i.e. all integral multiples of π

so, x = nπ when sin x = 0.

**If sin x=0 then x = __**

A. (2n+1)π/2

B. (n+1)π

C. nπ

D. nπ/2

**Answer:** C

**Solution:**

When know, sin x = 0 whenever x is 0, π, 2π, 3π,…. i.e. all integral multiples of π

so, x = nπ when sin x = 0.
