§3I see the player you mean.

§2PLAYERNAME?

§3Yes.

§2They need to learn Euler's Method.

§3I agree.

§2Its a numerical technique that can be used to approximate functions without knowing the original formula.

§3That's right. All you need is the slope and a starting X and Y condition.

§2First, you need to figure out the change in X and the number of steps. Dividing these will give you a step size.

§3Then, calculate the slope at the starting condition.

§2Your goal now is to figure out the equation of the tangent line. For this, use Point-Slope Form.

§3That would be Y-Y1=m(X-X1).

§2Using the next X from your step size, solve for Y using the previous condition for the X1 and Y1.

§3Repeat until you have your approximation!
