## Trigonometry (11th Edition) Clone

First we can find the angle $\theta$ by rotating counter-clockwise from the positive x-axis. We can then draw a line with a magnitude of $\vert r \vert$, starting from the origin and pointing in the opposite direction from the angle $\theta$.
$(r,\theta)$ is a point in polar coordinates and $r \lt 0$ First we can find the angle $\theta$ by rotating counter-clockwise from the positive x-axis. We can then draw a line with a magnitude of $\vert r \vert$, starting from the origin and pointing in the opposite direction from the angle $\theta$. Note that we must draw the line in the opposite direction from angle $\theta$ because $r \lt 0$
