What is Derivative of order more than one? So, Its easy to geometrically interpret the first order derivative in a graph by drawing a tangent to the curve of any function showing derivative as same the slope of the line but how can we draw a second order derivative on the same graph or how can we visualise this derivative of a derivative & the story get more complicated for more higher order derivatives? 

It's simply the derivative of the derivative of a function. So in the real world the second derivative would give you acceleration. A function that describes the position (p) at some time (t) of some object would have a first derivative that gives you the velocity and the second derivative would tell you the instantaneous rate of change of the velocity, or the acceleration.
