Hint: Derivation of function of variable x which is the rate at the value of function changes with respect to the change of variable. Integration is a method of finding the area to the x axis from the curve.

Let there is a curve, $y = f\left( x \right)$
Slope of the tangent $= \tan \theta$ $= \dfrac{{dy}}{{dx}}$ at (x,y)
$\int {\dfrac{{df\left( x \right)}}{{dx}}dx = f\left( x \right)} + C$
