Statement : The second derivative of the function represents the rate of change of first derivative.
\Definition of the derivative is instanteous rate of change.
\The first derivative is the instanteous rate of change of the function.
\The second derivative is the instanteous rate of change of the first derivative function.
\The second derivative of the function represents the rate of change of first derivative.
\Consider a example :
\A Velocity function is a rate of distance function.
\A acceleration function is rate of change of velocity function.
\Hence the statement is true.
