I’m not sure if Wolfram|Alpha has this capability, but I’d like a plot of the following set of points:
{(x,y,z) in R : x^2 + y^2 + z^2 = 5, y^2 + z^2 <= 3, and x>= 0}
Currently, every time I try to plot this, Wolfram interprets it as just x^2 + y^2 + z^2 = 5.
Any help is appreciated.
Equalities are handled by ContourPlot3D, with RegionFunction carving a subset defined by inequalities:
ContourPlot3D[
x^2 + y^2 + z^2 == 5, {x, -1, 3}, {y, -3, 3}, {z, -3, 3},
RegionFunction -> Function[{x, y, z}, y^2 + z^2 <= 3 && x >= 0]]
Pay attention to the double == instead of single =
