Question

What are the components of the vector between the origin and the polar coordinate `(7, (13pi)/12)`?

Answer 1

Components are `6.988` and `0.416`

Explanation:

The components of the vector between the origin and the polar coordinate `(r,theta)` are given by `rcostheta` and `rsintheta`.

Given the polar coordinates `(7,(13pi)/12)`, components in the instant case will be

`7xxcos(13pi)/12=6.988`

and `7xxsin(13pi)/12=0.416`
