Consider the differential equation dy dy 4=x? ху =1, where x <2 and y=1 when x= 0. (a) Use Euler's method withh=0.25 , to find an approximate value of y when x=1, giving your answer to two decimal places. The exact solution of this equation is y= v4-x² (sin" (0.5x)+0.5) (b) Show that your approximate value of y in (a) is greater than the true value of y. (c) Sketch the graph of y = f(x) for 0
