Consider the differential equationdydx$=4$x$,$with initial condition y$(0)=5.$ A$.$ Use Euler's method with two steps to estimate y when x$=1$: y$(1)($Be sure not to round your calculations at each step!$)$ Now use four steps: y$(1)($Be sure not to round your calculations at each step!$)$ B$.$ What is the solution to this differential equation $($with the given initial condition$)?$ y$=$ C$.$ What is the magnitude of the error in the two Euler approximations you found? Magnitude of error in Euler with $2$ steps $=$
