The Limit
behavior of a function near a point
The limit of a function f (x) at a point x = a describes the behavior of the function f (x)
near the point x = a.
If the values of f (x) accumulate near point

Antiderivative and The Indenite Integral
The idea of employing an inverse function is central when solving any equation:
x + 2 = 4 requires application of the function x 2, the inverse of x + 2, to the right hand side.
Thus x = 4 2 = 2
