Question

The least positive value x for which tangent x equals 0tanx=0 is

Answer 1

0° and 180°

Explanation:

Given tanx = 0

To get all positive value of x,

Tanx = 0

x = tan^-1x

x = 0°

Since the angle is positive, another angle for x will be found in the 3rd quadrant because tan is positive in the third quadrant.

x = 180+theta(3rd quadrant)

x = 180+0

x = 180°

The least positive values of x are 0° and 180°

Answer 2

the only value for x to make tanx = 0 is either 0 or 180 or 0 or pi.
