What is d^3x/d^3t mean?

what is d^3x/d^3t mean?


If x is a position function of time

dx/dt is velocity (time rate of change of position)

d^2x/dx^t is acceleration (time rate of change of velocity)

and d^3x/dt^3 is generally called "jerk", or time rate of change of acceleration


I guess it shall mean the 3rd derivative of a function x(t).


The 1st derivative = dx/dt

The 2nd derivative = d2x/dt2

The 3rd derivative = d3x/dt3


don't be a d3x/dt3
