Numerical Methods in Python Series - Rectangular Integration

Numerical Methods in Python Series - Trapezoid Integration

this tutorial will show you how to calculate integral with trapezoid method and draw the result with Python.


steps:
1. open Google Colab
2. do calculations for
f(x) = x**2
f(x) = x**4 + x**2 - x + 7
f(x) = x**2-2*x+3
f(x) = exp(-x**4)
f(x) = 1/(1 + x**2)
f(x) = exp(-x**2)

by running the first and second code

the first code will give you the result of the integral while the second code will draw you the result :)


4. observe the results and make analysis ;)

In the next tutorial we will compare integrations methods ;)
