Question

draw the directed distance of -13pi/6 on the unit circle?

Answer 1

Recall that a unit circle has 360° or in radians 2π

We are asked to draw the directed distance of -13π/6 on the unit circle.

We can convert from radians to degrees by multiplying the quantity in radians with 180/π

$-\frac{13\pi}{6}\times\frac{180}{\pi}=-390\degree$
