Solving Non Linear Equations - in Python

Numerical Methods in Python Series - Solving Non Linear Equations

this tutorial will show you how to solve non linear equation in Python.

the function is

f(x) = e^x - 5x^2

with interval between

a = -0.5 to b = 1.4

and step between each x
h = 0.1

steps:
1. watch previous video:
Numerical Methods in Python Series - Calculating Taylor Series for Exponential Function

2. create a code that compute the function with some interval of x (a to b) with step h = 0.1. if the sign is changed within the interval, then there must be at least one solution. choosing smaller h will give higher probability to find the interval with a single solution

3. the result show that the interval with solution is
[-0.40, -0.30] and [0.60, 0.70]

we will learn more about solving non linear equations in the next tutorial ;)

you can get the code from github:
