Solving integration problem using Feynman’s method / Wan Aina Farzana Wan Asri

Solving integration problems is very important as it is commonly appeared in wide range of fields and profession such as physics, mathematics, and engineering. There are four known theoretical methods used to solve integration problems which are integration by substitution, integration by trigonometric substitution, integration by partial fraction and integration by part. However, these theoretical methods are quite complicated and leads to long and laborious calculation. Therefore, researchers tend to use Feynman’s method which is quite simple and easy. In this project, seven theoretical methods which is integration by parts, integration by substitution, Gaussian integral, Power series, Properties of integral, Trigonometric substitution and Feynman’s method are chosen to solve complicated integration problems. The best method that has been choose is analysed using step and sub-step taken for both methods. The main purpose of this study is to determine the best methods for solving integration problems.
