Question

How do you convert `(6,-pi/5)` into rectangular coordinates?

Answer 1

`approx (4.854, -3.527)`

Explanation:

In general to convert the polar coordinate `(r, theta)` into rectangular coordinates, you just do `(rcostheta, rsintheta)`.

In the case of `(6, -pi/5)`, this would be
`(6cos(-pi/5), 6sin(-pi/5)) approx`(4.854, -3.527)#
