Question

What is the Cartesian form of `( 6, (-5pi)/2 )`?

Answer 1

The Cartesian form is `(0,-6)`

Explanation:

Use the equation, `x = rcos(theta)`, to find the x coordinate:

`x = 6cos((-5pi)/2)`

`x = 0`

Use the equation, `y = rsin(theta)`, to find the y coordinate:

`y = 6sin((-5pi)/2)`

`y = -6`
