Geogebra graphing help

Question

I'm trying to draw a wave in geogebra, something like the one on a pepsi logo. The wave is a vertical wave and I have no idea how to draw it.

I tried drawing a sine graph but I want a 'single' wave, which is 'vertical'

Any ideas?

Answer 1

A vertical wave is not a function of $x$. You might try $x = \cos y$, which is just a normal wave, except vertically.

Answer 2

• To reduce the “multiple” sine wave to a “single” one, multiply with a boolean value such as $x^2<\pi^2$, for instance. Just type sin(x) (x^2 < pi^2) into the input bar, and then hit enter.

• To transform a horizontal wave into a vertical one, use Rotate[...].

Answer 3

You can just reflect $\sin(x)$ in the line $y=x$ thus:
