    Mathematica Mathematica: Generate Surface Equation

    The equation doesn't have to be perfect, as long as it's a close approximation. I found another program that can do this. It has a database of hundreds of basic equations and it fits the best one automatically for you. I was wondering if Mathematica can do this. In the case of this example...

    Mathematica Mathematica: Generate Surface Equation

    Hi there, I just began using Mathematica today and I was wondering if there is a way to make the program generate an equation of a surface given a 3d array? What I need it to do is to give me an equation of the surface so that given any two variables I can find the value of the third one...

    Harmonic Oscillator Problem: Consideration & Solutions

    Correct me if I'm wrong but wouldn't resonance require an external driving force? This problem doesn't have an external driving force.

    Harmonic Oscillator Problem: Consideration & Solutions

    Problem: Consider a harmonic oscillator of undamped frequency ω0 (= \sqrt{k/m}) and damping constant β (=b/(2m), where b is the coefficient of the viscous resistance force). a) Write the general solution for the motion of the position x(t) in terms of two arbitrary constants assuming an...
