|dw:1347495306598:dw| That's cos and sin right? How do I add them together? Does the new graph line go higher than both of those? Or in between? Im confused :/ Thanks!

unless you have an equal sign there....you can't graph it

since sin x+cos x=1/2 sin 2x then y=1/2 sin 2x. The graph is just the sin graph you made.

I made a sinx graph and a cosx graph, sorry I don't understand what you mean. Can someone please draw out for me what the new graph will look like in comparison to the sin and cos? Thannks

Here is an image of a graph from wolframalpha.com. Is sort of like a computational engine, I think... But it's very helpful. I typed, "sinx+cosx=y,sinx=y,cosx=y". When you graph them, you really can take the height of sin(x) and put the hieght of cos(x) on top of that!

Thanks theEric!!

My pleasure! Thanks! You can also look at the unit circle to compare sin(x), cos(x), and sin(x)+cos(x).
