convert the equation y^2 = 2x -x^2 into polar form.

convert the equation r = 2tan(theta) into rectangular form.

I'm not really sure what either of these mean. I vaguely understand polar coordinates, but I'm not sure how to convert equations back and forth between polar and rectangular. Please help =(
