Question

Convert the polar coordinates to rectangular.
(-3.5, 0.916)

Answer 1

help?

Answer 2

These coordinates are in polar currently?\[\Large\rm (r,~\theta)=(-3.5,~0.916)\]

Answer 3

yes, and need converted to (x,y)

Answer 4

Use these for converting from `Polar` to `Cartesian`,
\[\Large\rm x=r \cos \theta, \qquad\qquad y=r \sin \theta\]Just use a calculator from there ^^

Answer 5

thats what I did, but it's not accepting that answer

Answer 6

wants exact values if possible...

Answer 7

I get (-2.13, -2.78) when rounding to two decimal places

Answer 8
