Question

How do you find the rectangular coordinates given the polar coordinates `(14, 130^circ)`?

Answer 1

The point is `(14cos(130^@),14sin(130^@))~~ (-8.99, 10.72)`

Explanation:

`x = rcos(theta) and y = rsin(theta)`

`x = 14cos(130^@) and y = 14sin(130^@)`

The point is `(14cos(130^@),14sin(130^@))~~ (-8.99, 10.72)`
