Understanding L'Hôpital's rule

-
L'Hospital's rule is the definitive way to simplify evaluation of limits. It does not directly evaluate limits, but only simplifies evaluation if used appropriately.
In effect, this rule is the ultimate version of ‘cancellation tricks’, applicable in situations where a more down-to-earth genuine algebraic cancellation may be hidden or invisible.

Introduction to Integral Calculus

In mathematics, an integral assigns numbers to functions in a way that can describe displacement, area, volume, and other concepts that arise by combining infinitesimal data. Integration is one of the two main operations of calculus, with its inverse operation, differentiation, being the other. Given a function  f  of a real variable  x  and an interval  [a, b]  of the real line, the definite integral {\displaystyle \int _{a}^{b}f(x)\,dx} is defined informally as the signed area of the region in the  xy -plane that is bounded by the graph of  f , the  x -axis and the vertical lines  x  =  a  and  x  =  b . The area above the  x -axis adds to the total and that below the  x -axis subtracts from the total. The operation of integration, up to an additive constant, is the inverse of the operation of differe...
