Evaluate $arctan (- \sqrt{3})$ $arctan (-sqrt3)$

Ans: $\frac{2 π}{3}$ $(2pi)/3$ and $\frac{5 π}{3}$ $(5pi)/3$

Explanation:

Trig Table of Special Arcs and unit circle give -->
$tan x = \sqrt{3}$ $tan x = sqrt3$ --> arc $x = \frac{2 π}{3}$ $x = (2pi)/3$ and arc $x = \frac{2 π}{3} + π = \frac{5 π}{3}$ $x = (2pi)/3 + pi = (5pi)/3$
