The coordinates of a point on a circle can be described in either a cartesian or polar system. For the point in polar coordinates ,(r, Angle sign) = (sqrt(2), (pi/4)), find the cartesian coordinates using the following transformation: x = r*cos(Angle sign) and y = r*sin(Angle sign) Use two variables named r and theta to solve the problem. Do not use spaces or semi-colons and store the answer in a variable named y. The code to calculate the y coordinate is :?
