arctan$ 0=0$

Work Step by Step

lnverse Tangent Function $y=\tan^{-1}x$ or $y=$ arctan $x$ means that $x=\tan y$, for $-\displaystyle \frac{\pi}{2} < y < \frac{\pi}{2}$. ---------- In the interval$\quad -\displaystyle \frac{\pi}{2} < y < \frac{\pi}{2}$ , we find $y=0$ to be such that $\tan 0=0$. So, $y=\arctan 0=0$
