# Is -3 pi the same as 2 pi?

## Say if you want find t when t=-3 pi, how would you do it?

$2 \pi > \left(- 3 \pi\right)$ and not equal.
$\pi = \frac{22}{7}$
Hence $2 \pi = 2 \cdot \left(\frac{22}{7}\right) = \frac{44}{7}$
Likewise, $- 3 \pi = - \frac{66}{7}$
As $- \frac{66}{7} < \frac{44}{7}$, $- 3 \pi < 2 \pi$
