Problem 1: Consider the following Initial Value Problem (IVP) where ? is the dependent variable and ? is the independent variable: ?′=sin(?)∗(1−?) with ?(0)=?0 and ? ≥ 0
Note: the analytic solution for this IVP is: y(t) = 1+(y_0 - 0)e^ cos(t)-1
Part 1B: Approximate the solution to the IVP using the Improved
Euler’s method with the following conditions: Initial condition
?0=−1/2; time step ℎ=1/16; and time interval ?∈[0,20]
+ Derive the recursive formula for the Improved Euler’s method
applied to this IVP
+ Plot the Improved Euler’s method approximation
+ Plot the absolute error between the approximation and the exact
solution using a semilog plot
I'm having problems correctly codding these steps. Please type out.
