How do you find the rectangular form of (r^2)cosø?
I'm trying to figure out how to find the rectangular equation for (r^2)cosø
I know:
x=rcosø
y=rsinø
tanø=y/x
r^2=x^2+y^2
r=√(x^2+y^2)
Please help! Thank you!

r^2 * cos(t) =>
r * cos(t) * r =>
x * sqrt(r^2) =>
x * sqrt(x^2 + y^2)
You do not really have an equation but the expression converts to:
xâ{x² + y²}
