Best ResponseYou've already chosen the best response.0dw: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!

Best ResponseYou've already chosen the best response.0since sin x+cos x=1/2 sin 2x then y=1/2 sin 2x. The graph is just the sin graph you made.

Best ResponseYou've already chosen the best response.0I 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

Best ResponseYou've already chosen the best response.1Here 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!

Best ResponseYou've already chosen the best response.1My pleasure! Thanks! You can also look at the unit circle to compare sin(x), cos(x), and sin(x)+cos(x).
