hi.

can i have a densityplot in 3d?

i want to plot a sphere.

i have a function f(r, theta) which is supposed to be the temperature of my sphere. can i plot my function f such that it is like a densityplot on my sphere? i cant seem to find the right command for this.

thanks!

hi.

i have this function f(r,theta) which i want to graph in polar/cylindrical coordinates. but when i try to plot it, the coordinate system seems to be in cartesian because my horizontal axis becomes my values for r and vertical axis becomes my values for theta.

How can i plot my function f(r,theta) in polar/cylindrical coordinate such that r=0..1, and theta=0..2*Pi?
