Hi. I want to plot 1/sqrt(x^2+y^2+z^2) in Mathematica ver10.0. Could anybody tell me how to plot 1/sqrt(x^2+y^2+z^2)?
Hello community, I am university student. I started to use Mathematica in few days ago. I want to solve the following simultaneous equations. I tried "Solve" and "NSolve", but I could not obtain answers. Do I make a mistake using these functions?...
