equation containing sine and cosine of matice

Hello;

How can I write the program of equation containing the sin and cosins with cos(alpha) varis to 0 to 180 ans sin(phi) varies to 0 to 360. knowing that the S11 and S12 are the elements of matrice

this is equations

E=(1/((s11*(sin(alpha)*cos(phi))^4)+(2*s12*((sin(alpha)*cos(phi))^2)*((sin(alpha)*sin(phi))^2))

with:

x= cos(alpha)sin(phi)

y=sin(alph)sin(phi)

z=cos(alpha)

Thank you
