Use Euler’s Method: ????????????????=???? ????????????????=−????????−????3+????cos(????) ????(0)=1.0 ????(0)=1.0 ????=0.4 ????=20.0 ℎ=0.01 ????=10000 ▪ Write the data (y1, y2) to a file named "LASTNAME_Prob1.dat" Example: If your name is John Doe – file name would be "DOE_Prob1.dat" ▪ Plot the result with lines using GNUPLOT (Hint: see lecture 08) ▪ Submit full code (copy and paste). Plot must be on a separate page. ▪ Run the code again and plot the result for: ????=0.1 ????=11.0
