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. http://img822.imageshack.us/img822/6787/poly.jpg [Broken] Uploaded with ImageShack.us any help would be much appreciated. thank you.
