Question

How do you find the point on the unit circle that corresponds to 5pi/4?

Answer 1

The point is `pi/4` below the negative X-axis at a distance of `1` from the origin.

Explanation:

The coordinates of the point are:
`color(white)("XXX")`in polar form: `(1,(5pi)/4)`
`color(white)("XXX")`in Cartesian form: `(-sqrt(2)/2,-sqrt(2)/2)`
