Google Math Tip
Need to plot a function?
Just punch your request into Google to get an instant plot.
Example: to plot the function f(x)=x^2 just enter plot x^2 into Google. Of course, it can also handle much more complex functions, for example try plot x^3+1/x or try one of my favorites, just enter plot 1/(1+x^2)
