Question

What are the components of the vector between the origin and the polar coordinate `(3, (5pi)/12)`?

Answer 1

`barv = 3cos((5pi)/12)hati + 3sin((5pi)/12)hatj`

Explanation:

let `barv` be the vector with components `v_xhati + v_yhat j`

`v_x = 3cos((5pi)/12)`

`v_y = 3sin((5pi)/12)`

`barv = 3cos((5pi)/12)hati + 3sin((5pi)/12)hatj`
