Question:
Hi, I am in Calc III at a college..... and Now we are working on gradients, 3-d graphs polar equations, etc.
I sometimes have a problem drawing/visualizing these 3-d graphs.....any suggestions on how to overcome this will be VERY GRATEFUL!
I am new to the bbs.....so I do not know how to find out if it has been answered or not could someone mail me and tell me where to look for the responses.


Replies:
In JHS I spent one quarter learning drafting as part of wood shop. This taught me perspective drawing and plan drawing which, I think, greatly helped with the problem your struggling with. Nowadays computers a VERY useful for visualizing 3-D data, graphs and plots. See if you can find an SGI machine and someone who knows how to use it at your college.
