What is the correct expression for the slope of the tangent line in polar coordinates?
dy/dx = r'(theta) * sin(theta) + r(theta) * cos(theta)
dy/dx = r(theta) * cos(theta) - r'(theta) * sin(theta)
dy/dx = r(theta) * sin(theta) + r'(theta) * cos(theta)
dy/dx = r'(theta) * cos(theta) - r(theta) * sin(theta)
