Kahn ... To start off my teacher does not allow calculators in class, and I do not have the money to go and buy one myself .. I really like your website and works but I have to say I never had thought you would use a calculator in one of your videos knowing how intelligent you are .. I'm extremely struggling in this subject and using a calculator and not explaining and using a device is shocking. Do you have any videos showing how to do these "without" using a calculator?

Like, I know by now you're probably in college or something, but familiarizing yourself with a graphing can be useful especially when learning more difficult process and you don't nesisarily have any time to waste on this when you have more things to focus on. Also, using a calculator doesn't make you any less smart.

haha...without going to deeper debate, i have a HP-48G, which cost about the price of a netbook about 12 years ago!!! Its still very powerful today in my opinions as it can do 3D graph...so i thought it was a very good investment!! :)
