9. To find the approximate values, set y 1 5 2 y 1 sin x and use EULERT with initial values x 5 0 and y 5 0 and step size 0.1 for 10 points. The exact values are given by y 5 } 1 5 } ( e 2 x 2 2 sin x 2 cos x ). 10. To find the approximate values, set y 1 5 x 2 y and use EULERT with initial values x 5 0 and y 5 2 2 and step size 0.1 for 10 points. The exact values are given by y 5 x 2 1 2 e 2 x . 11. To find the approximate values, set y 1 5 2 y ( x 1 1) and use IMPEULT with initial values x 5 2 2 and y 5 2 and step size 0.1 for 20 points. The exact values are given by y 5 2 e x 2 1 2 x . 274 Section 6.6 x y 1 2 improved Euler y (exact) Error 2 2 2 2 0 2 1.9 1.6560 1.6539 0.0021 2 1.8 1.3983 1.3954 0.0030 2 1.7 1.2042 1.2010 0.0032 2 1.6 1.0578 1.0546 0.0032 2 1.5 0.9478 0.9447 0.0031 2 1.4 0.8663 0.8634 0.0029 2 1.3 0.8077 0.8050 0.0027 2 1.2 0.7683 0.7658 0.0025 2 1.1 0.7456 0.7432 0.0024 2 1.0 0.7381 0.7358 0.0023 2 0.9 0.7455 0.7432 0.0023 2 0.8 0.7682 0.7658 0.0024 2 0.7 0.8075 0.8050 0.0024 2 0.6 0.8659 0.8634 0.0025 2 0.5 0.9473 0.9447 0.0026 2 0.4
