A high school student in AP calc class, so please bear with, hopefully this is simple for all you college kids:

dy/dx x~4 (t)tan t

I have no idea what you just said. Can you rephrase your question?

What does ~ mean?

This doesn't make sense for a number of reasons. If you are supposed to take the derivative with respect to x you would notate like this: $\frac{d}{dx}f(x)$ When you put $\frac{dy}{dx}=f(x)$, you are saying that y is a function of x and you have already taken the derivative. In your problem you have two variables, x and t. And as ThePerfectHacker said, what does ~ mean? Anyway, we'd all love to help but we're kinda confused on what you're asking.
