Just go to a google search bar and type in a function.
For instance, cos(pi*x/5)
You'll get a graph that has some interactive features.
Separate multiple functions with commas.

Let's do two functions today. As sometimes happens, in this case we're not so interested in the functions themselves as the fact that these functions happen to be part of a general class of functions. Just as we can classify the real numbers as even, odd, or neither (numbers like pi, 1/2, and the…
"So," Herr Schrodinger says to us, "I'm looking for a function of x. It needs to be equal to the negative of its second derivative, up to a constant factor. When x is zero, the function itself should be zero. And when x equals L for some constant L greater than zero, the function also needs to…
The Exponential Function. I think this is the first time we've done it here. It won't be the last. You could write a book about it, and someone probably has. Here's the usual picture:
This graph isn't as pretty as the usual, because I'm at home with my old copy of Mathematica 5 instead of the…
Last week we did the sinc function. Let's do it again!
The function, to refresh our collective memory, is this:
Now I was thinking about jumping right into some contour integration, but on actually doing it again I see that it's a little hardcore for one post so eventually when we do it we'll…
Interesting AND cool.
