Question

Find the rectangular coordinates of the point with the polar coordinates (8, 3 divided by 2 pi).

Answer 1

Have you considered the sine and cosine of the given angle?

Answer 2

\(\large \begin{array}{llll}
\left(8,\frac{3}{2}\pi\right)\\
\ \uparrow\quad \uparrow \\
\ r\quad \theta
\end{array}\qquad
\begin{array}{llll}
x=rcos(\theta)\\
y=rsin(\theta)
\end{array}\qquad (x,y)\)

Answer 3

so would it be (8,0) @jdoe0001

Answer 4

"3 divided by 2 pi" Is that \(\dfrac{3}{2\pi}\)? Sure sounds like it.

Careful with notation.

No, it's not (8,0). Think about \(3\pi/2\). Is that the positive y axis or negative y axis?
