Question

What are the components of the vector between the origin and the polar coordinate `(15, (-pi)/4)`?

Answer 1

`x=(15sqrt2)/2`
`y=(-15sqrt2)/2`

Explanation:

`x=r*cos theta=15*cos (-pi/4)=(15sqrt2)/2`

`y=r*sin theta=15*sin (-pi/4)=(-15sqrt2)/2`

God bless...I hope the explanation is useful.
