# Euler's method(1st-derivative) Calculator

## Calculates the solution y=f(x) of the ordinary differential equation y'=F(x,y) using Euler's method.

 The initial condition is y0=f(x0), and the root x is calculated within the range of from x0 to xn. $\normal \\\vspace{10}y'=F(x,y)\hspace{30} y_0=f(x_0)\rightarrow\ y=f(x)\\$

IMPORTANT INFO: To use custom number of partitions use source code editor by using F-12, and then click select element and click on number in box. There will be stuff like <option value="XYZ">10</option> change XYZ (not 10 in between) to your number of partitions. Hope you'll be able to do what you wanted to do.

Would be nice to specify step size instead of number of steps, but otherwise good approximation

I had to change the HTML value for the select input of the partitions in order to get the number of partitions that I wanted.
