Function for Sine Wave

[I'mLearning]

I want to find the function for the following wave:




What does the formula look like? I know that the larger wave is a simple sine function.

I know that the larger wave is a simple sine function.

Can you write a mathmatical expression for the larger wave?

Do you mean something like this?



What do you think I might have added to a basic sine? (I started with just sin(x).)

Yes, my equation was [math]y=\sin\left(x\right)+.1\sin\left(20x\right)[/math]
