Q3M) Given the IVP x²y' +2xy = cosh x, y(1)=0: a) Determine the explicit solution by providing and justifying all steps needed. b) Ignoring the solution that you found in part a), construct Euler's formula needed to estimate y(1.6) in three steps and determine whether the corresponding estimate would be an overestimate or an underestimate. As always, you need to provide valid arguments in support of your conclusion.
