I would like to superimpose Cos[x] {x,Pi/4,Pi/2} right on top of Sin[x] {x,0,Pi/4}. I think the x axis would only be a length of Pi/4 and it would show both Cos[x] {x,Pi/4,Pi/2} and Sin[x] {x,0,Pi/4}. I would also wanted to superimpose Cos[x] {x,Pi/4,Pi/2} on top of Cos[x] {x,0,Pi/4}. Using the methods most people have been giving me I would get Cos[x]{x,0,Pi/2}. I would like to put the 2 plots on top of each other.
