question 57

Multiple Choice

Solve. Round your results to four decimal places.
-Use the Euler method with $d x = 0.2$ to estimate $y ( 3 )$ if $y ^ { \prime } = - y / x$ and $y ( 2 ) = 3$ . What is the exact value of $y ( 3 )$ ?

• A) \(\mathrm { y } \approx 0.7895\), exact value is \(2.0000\)
• B) \(\mathrm { y } \approx 1.9286\), exact value is \(1.5000\)
• C) \(\mathrm { y } \approx 1.1053\), exact value is \(6.0000\)
• D) \(y \approx 1.7368\), exact value is \(3.0000\)
