1. The problem statement, all variables and given/known data I have calculus, and a lot of tasks ask for drawing of the functions in 3 dimentions. I have problems thinking of how to do this, often it can be a parabolid or other Objects. Example, one I cant think of how im suppose to Draw, here Im going to solve for Stokes (that is a pretty easy function) x^2 +y^2 +5z =1 , where z≥0. Is there any good technique to use for drawing With Three variables? 2. Relevant equations I dont know what to use here 3. The attempt at a solution I think that if I put z=0, you get a circle in the xy-plane With a radius 1, but when z=1, I get X^2 +y^2 =-4, so the New radius is -4 ( or is it √-4?) i dont think im thinking correctly here.
