Question

Find the rectangular coordinates of the point with the polar coordinates (-7, 5pi/3)

Answer 1

ahh the easiest of them all :)
Given the polar coordinates \((\color{green}r,\color{orange}\theta)\)
the rectangular coordinates are:
\[\Large (\color{red}x,\color{blue}y )= ( \ (\color{green}r\cos(\color{orange}\theta)\quad , \quad\color{green}r\sin(\color{orange}\theta) \ )\]

Simple, no? :P

Answer 2

Very simple! Just inputted values and came up with -7/2, 7sqrt3/2
