Hey guys i need help with this question for an assignment.
Find a Cartesian equation for the curve and identify it:
r = 2sin(θ) + 2cos(θ)
i tried multipliying everything by r, getting:
r^2 = 2rsin(θ) + 2rcos(θ)
then making r^2 = x^2 + y^2 and making rsin(θ)=y and rcos(θ)=x.
but that didn't work :/.
