Question

Anyone want to help with graphing 3d shapes? Because I need help with imagining how a this function looks like.....f(x,y)=(y-2x)^2

Answer 1

I use this java app for my 3-D graphing needs: http://dlippman.imathas.com/g1/Grapher.html

Answer 2

To graph your particular function, select "z = f(x,y) Surface" in the drop-down menu saying "Choose a graph to add."

Then, in the z = f(x,y) input box, type in (exactly)
(y - 2*x)^2.

Adjust the window size by clicking on the Bounds tab on the top of the app. Check every box (it seems to work better that way), and adjust the mins and max to your preference.

Answer 3

Thanks....the computer I am using right now can't open the program right now so I can check it out later

Answer 4

In that case, here's another link for future access: http://dlippman.imathas.com/g1/GrapherLaunch.html

There's also a 2-D and Differential equation solution grapher.

Answer 5

Sweet that actually helps a lot thanks!
