David's Octave Assignment

I followed the Instructions "Read this first!!" For acquiring a copy of Octave. I just copied it to my flash drive from a computer lab pc.

I played around with Octave as instructed, But I still don't understand it very well. I plotted a couple graphs, but I don't understand the proper syntax format for Octave, I got many syntax errors because I'm not familiar with the symbols and code for entering functions and commands.

If I enter: y=x; plot (x,y)

then it plots the graph of y=x.

But when I enter: y=x^2; plot (x,y)

it says: error: For A^B, A must be square.

I'm confused, but Hopefully I'll figure out more in the future.

I spent 1 hour installing this program and trying to figure it out. David
