# Spherical Plots

Only two students submitted ``spherical creations". We will have a creative project in the end, where everybody will be creative. In any case, if you still have a spherical plot lying around you want to share, send it in. Brian: s cos^{2}(3 s) + s sin

^{2}(5 t) Soy: 21 + Cos[30 s] + (Sin[15 t])^2 + 8 + Cos[34 s] + Sin[10 t]
