Today I studied Euler's Method. I decided to see a Khan Academy video regarding Euler's Method in order to freshen up on the key concepts of it (https://www.khanacademy.org/math/differential-equations/first-order-differential-equations/eulers-method-tutorial/v/eulers-method). This method is the simplest of numerical integration. At the end of my study session, I realized that three very important concepts are needed to apply Euler's Method.
1) A starting point (x.y)
2) The change in "x"
3) The slope (of each line segment)
By using the chart below, we are able to easily apply this method:
(x,y) 
 | Δx or dx | 
dydx 
 | 
dx(dydx)=dy 
 | 
(x+dx,y+dy) 
 | 
|   |   |   |   |   | 
|   |   |   |   |   | 
|   |   |   |   |   | 
|   |   |   |   |   | 
*Lastly, a very important thing I discovered is that Euler's Method is basically all repetition. You just need to keep on repeating steps in order to discover the desired "x-value."
