If tan x = 0 then x = _________(a) nπ(b) (2n+1) π/2(c) (n+1) π(d) nπ/2The question was asked in unit test.Question is from Trigonometric Functions in division Trigonometric Functions of Mathematics – Class 11

Answer»

The correct option is (a) nπ

Easy EXPLANATION: We KNOW, TAN X = sin x / cos x. So, tan x will be zero wherever sin x is zero except the points where cos x is also zero. We know there is no point where sin x as well as cos x both are zero. So, tan x = 0 => x=nπ.
