The letters r and theta represent polar coordinates. Write the equation using rectangular coordinates (x, y). r = cos theta x^2 + y^2 = y x^2 + y^2 = x (x + y)^2 = x (x + y)^2 = y (x + y)^2 = x

Solution

1. r=cos theta

   multiplying both sides by r

r²= r cos theta

and r cos theta=x

and r²=x²+y²

x²+y²= x

Correct option is B
