This approximates the area under the curve by dividing the total area into small trapezoids. $$I = \frach2 [y_0 + y_n + 2(y_1 + y_2 + ... + y_n-1)]$$

This is the most widely used method for finding roots. It uses the tangent to the curve at an approximate point. Formula: $$x_n+1 = x_n - \fracf(x_n)f'(x_n)$$ free pdf on numerical analysis by dutta jana top

Even if you cannot find a free pdf on numerical analysis by dutta jana top today, you can still ace your exams using the following strategy: This approximates the area under the curve by

This is an iterative method utilizing the tangent line to the curve. It is favored for its speed but requires a good initial guess.

To convince you that this book is worth the search, here is a typical "golden example" from their section on Newton-Raphson Method as found in the "Top" edition: Problem: Find the real root of the equation

Problem: Find the real root of the equation ( x^3 - 2x - 5 = 0 ) correct to three decimal places. Solution Approach:

The Dutta & Jana text does not just show this; it provides a C-language algorithm (in older editions) or a pseudo-code (in newer "Top" editions) in the margin.
