Solving an Initial Value Problem Using Euler's Method

Click For Summary
SUMMARY

The discussion focuses on solving the initial value problem defined by the differential equation y' = 2y - x with the condition y(11) = 6 using Euler's Method. The correct interpretation of the initial condition is clarified, establishing that y0 = 6 and x0 = 11. The formula for Euler's Method, yn = yn-1 + F(xn-1, yn-1)(h), is confirmed as the appropriate approach for iterative calculations with a step size of h = 0.2.

When solving the initial value problem y ' = 2y-x, y(11)=6 using Eulers method with h=0.2, y0=?

I know how to solve Euler's equations with the formula yn = yn-1 + F(xn-1 + yn-1)(h), however I'm not quite sure how or what they want in this particular case. Can anybody please help me out if you have an incline? Thanks.

Since you are told "y(11)= 6", obviously y0= 6 (and x0= 11).
 
Thanks HallsofIvy! I thought that it meant the eleventh y was 6.
