Need a graph

  1. Jun 10, 2010 #1
    Hello I am appealing to the computer savvy bunch here and asking for a graph.

    I need the graph to show a function that is of the form (Acos(x)+Bsin(X)) it can be simple.... just anything harmonic I dont' even need the function you can just draw it. and then I need a polynomial that has the same zeros.

    again this just needs to look good, the math doesn't have to be correct you can Photoshop it if that's easier. I have included my drawing of it by hand.

    Hello i suggest you to use gnuplot...you can plot any function..and export to jpg or eps or pdf..
    have a look at the attachment..one is f2(x)=sin(x) and other is f(x)=2sin(x).
