*Geometrical Meaning of integration

is called Integral or primitive of y w.r.t. x or anti-differentiation.

Here, ydx is area of elementary rectangular strip of thickness dx.

Thus gives the total area bounded by the all the elementary strips of the curve represented by the function

y = f (x) with the x-axis between the limits x = a to x = b. As convention upward areas are taken as positive and downward area negative.
