My supervisor wants me to do the plot in cartesian coordinates now, but I don't think it's as simple as typing coords=spherical into the code. I am meant to use the following equations to do this

x₀=r₀sinθ₀cosΦ₀

y₀=r₀sinθ₀sinΦ₀

z₀=r₀cosθ₀

x=rsinθ₀ cosΦ₀

y=rsinθ₀ sinΦ₀

z=rcosθ₀

During expansion, only r varies, and θ, and Φ stay constant obviously.

I've literally typed the equations into Maple, with Φ_0, θ₀ represented by the iterations i*Pi, and j*Pi and tried to plot x,y and z but Maple keeps refusing to produce any plot.
