I ran this, and didn’t get any errors: a=f(x,y)=x^2+y g1= derivative(sin,0.0) g2=derivative(a) print(g1) print(g2) I don’t however, have an output for the function, nor can I find a sum, when I put in f(3,2) for f(x,y).

Please post a self-contained MWE, including a using for the library which provides derivative. [image] Please read: make it easier to help you Meta Discussion Welcome to the Julia Discourse! We are enthusiastic about helping Julia programmers, both beginner and experience…

using Calculus using Plots x = 1:10; y = rand(10, 2) # 2 columns means two lines a=plot(x, y) g1= derivative(sin,0.0) print(g1) display(a) this gives the derivative of sin 0, in the terminal, and the plot flashes on screen, for about a second or so.

I think I need to run this in the REPL, but I can’t get the REPL to open. Before, I just put $julia in the shell.

It seems that there are at least 3 different problems here: your Julia installation, plotting, derivatives. If Julia does not run from the command line, I would start with the first one.

I got that all sorted. It works as it should, Only thing left to test is exporting with Taro or Weave.
