How to design a compound parabolic concentrator by using Equation Driven Curve

Guys,

I have the equations to draw a perfect parabola shape but I am struggling to get it written in the right way in the equation driven equation in solid works.

I want to type this equation:

y=(x^2)/(2*(1+sin(z))) , where z is the angle in degrees which is equal to 30

Can anyone help me in that

Regards;
