Function for a sinusoidal camel plot? ![enter image description here]( Is this kind of function possible? If so, what would the equation look like? I can get the camel like notch with a an exponent in a sin, such as sin(x^2), but I only get one notch.

There are loads. Try $\sin(x)+\cos(2x)$, for instance.
