If dy/dx = tan(?), is possible to relate d²y/dx² with some function of theta too?

You aren't saying exactly what you mean! If, as I suspect, "theta" is the angle the tangent to y= f(x) makes with the xaxis, so that "dy/dx= tan(theta)" is one definition of the derivative, then NO, the second derivative cannot depend on theta. We can, in fact, take any value for both first and second derivatives at any one value of x.
