when $\theta$ is small $\approx 0^{\circ}$ then $\sin\theta=\tan\theta=\frac{\pi\theta}{180^{\circ}}$

Work Step by Step

The table of $ sin\theta$, $\tan\theta$ and $\frac{\pi\theta}{180^{\circ}}$ given on angles from $0^{\circ} - 4^{\circ}$ with step $0.5^{\circ}$. There $ sin\theta$, $\tan\theta$ and $\frac{\pi\theta}{180^{\circ}}$ values are increasing and they are equal only when angle is equal to 0 degrees.
