    There's a good application: Acceleration of an object is the second derivative of its position function.

    Well when differentiating twice you can get the Point Of inflexion on a curve.

    First derivative is your rate of change of the function, it tells you if your function is going up, down at a point. Second derivative is the rate of chance OF the rate of change, it tells you if the graph of the function is concave up or concave down at a point

    so I find the derivative of \[f(x)=xe^x\] using the product rule, then i derive it again?
