Is there any way to manipulate a sine function such that the amplitude when it is positive is larger than when it is negative?

Herp derp. I think I have an effective solution. Not quite what I was looking for, but. Just a slight vertical shift upwards. More of the wave will then lie above the x axis. If anyone has something better, do chime in!

What @Mariah said. Your sine function would have an amplitude of 1.5 centered around y = 0.5.

It wouldn’t fit the definition of a sine wave in that case

f(x) = (sin x) * (exp(sin x))

@bob….you’re a genius.

@Mariah Always happy to help! :)

Out of curiosity, what do you need this for?

I have a project in the works. I’ll PM you.

Isn’t the maximum of (sin x) * (exp(sin x)) the number e and its minimum -1/e?

@BonusQuestion Yes.

The details aren’t important. @bob_‘s function does what I need, although I would still be interested if there were other ideas.

Well, then take any continuous function f(x) over [-1, 1] and consider f(sin(x)). It seems to do what you want to do. You can choose f(x) to be strictly increasing or strictly decreasing to make sure it comes out to have only one “wave”.

More precisely if maximum and minimum values of f over [-1, 1] are M and m, respectively, then the function g(x) = (3 f(sin x) – (M+2m))/(M – m) has a maximum of 2 and a minimum of -1.
