Question

What is the Cartesian form of `(12,(14pi)/3))`?

Answer 1

x: -6
y: 10.39

Explanation:

Use conversion formula:

`x = r cos(theta)`

`y = r sin(theta)`

Whadaya know, the cosine of `(14 pi)/3 = -0.5`, so the x coordinate is 12 * -0.5 = -6

the sine of this angle is 0.866, so the y coordinate is 12 * 0.866 = 10.39

GOOD LUCK
