my calculator is set to degree but when I do sin(pi) it gives me the answer as 0.054804 which is weird because the answer is obviously 0 in both DEG and RAD

    $\begingroup$ In degree $\sin(\pi)$ is just $\sin(3.1\dots)$. In degree, $\sin(x) = 0$ implies that $x = k180$ for some $k\in\mathbb{Z}$. $\endgroup$ – Mark Oct 26 '17 at 21:32

Yeah, but remember that $\pi \mathrm{\: rad}=180^{\circ}$, so $\sin(\pi^{\circ}) \neq \sin(\pi \: \mathrm{rad})$. $\sin(\pi)=\sin(180^{\circ})=0$. Check that your calculator is in RAD, not in DEG nor GRAD.
