Hi PF!
If I'm trying to plot something in mathematica, say ##y=x^2## and then I want to find out what ##y## is when ##x=3##, how would I do this?
Thanks so much!
I should add, the function I'm inputting in is a numerical solution to a non-linear ODE, so it's not as easy as simply inputting ##3^2## in the above example.
