I can't seem to find the solution to graph the sum of two functions.
For example, y1=sin(524πt), y2=sin(784πt)
I've tried y3=y1+y2, and it doesn't work. Can you give me some advices?

Thanks!

Hi duskube and welcome to the UCF!

You could use functions to do this. First, go into Main mode and type in:

Define f(x)=2x+3 or some other expression
Define g(x)=4x+1 or your second expression.

Then go into graph mode and type y1=f(x)+g(x)

Then you should graph your sheet to find that it displays

y=6x+4.

Hope that this helps,

y3=y1(x)+y2(x) works as well, if I remember correctly.

Thank you very much!
