Answer 1

x = r*cos(theta)
y = r*sin(theta)

Answer 2

your r is -3
your theta is -3pi/4

Answer 3

I got decimals. the answer has to be in radians.

Answer 4

radians is an angular measurement. you are asked to give dimensional coordinates, which arent in units of radians

Answer 5

make sure you are using radians setting in your calculator when you take the cosine and sine of the angle

Answer 6

so decimals are OK for the coordinates?

Answer 7

yes
