Key Idea 8.5. 1 Guidelines for Choosing an Integration Strategy (a) Simplify the integrand, if possible. (b) See if a ?simple? substitution will work. (c) Identify the type of integral. (d) Relate the integral to an integral we already know how to do. (e) Try multiple techniques. (f) Try again.

If the functions are known analytically instead of being tabulated at equally spaced intervals, the best numerical method of integration is called Gaussian quadrature. By picking the abscissas at which to evaluate the function, Gaussian quadrature produces the most accurate approximations possible.

Differentiation is used to study the small change of a quantity with respect to unit change of another. (Check the Differentiation Rules here). On the other hand, integration is used to add small and discrete data, which cannot be added singularly and representing in a single value.

The list of basic integral formulas is given below: ? 1 dx = x + C. ? a dx = ax+ C. ? xn dx = ((xn+1)/(n+1))+C ; n?1. ? sin x dx = ? cos x + C. ? cos x dx = sin x + C. ? sec2x dx = tan x + C. ? csc2x dx = -cot x + C. ? sec x (tan x) dx = sec x + C.

Integration by Substitution Method. Integration by Decomposition. Reverse Chain Rule. Integration Using Trigonometric Identities.

In practice, Feynman's trick is often applied to integrals with a single variable; the idea is to artificially introduce a second variable and then build a differential equation in terms of derivatives with respect to 1 Page 2 the new variable.

How many Types of Methods of Integration are there? There are many methods of integration that we use but the most common ones are 5, namely Integration by Parts, Method of Integration Using Partial Fractions, Integration by Substitution Method, Integration by Decomposition, and Reverse Chain Rule.
