Y′=3cos(t)−6y, y(0)=0 (a) Find approximate values of the solution of the given initial value problem at t= 0.1, 0.2, 0.3, and 0.4 using the Euler method with h=0.1. Round your answers to three decimal places. y(0.1)≈ y(0.2)≈ y(0.3)≈ y(0.4)≈ (d) Find the solution y=φ(t) of the given problem and evaluate φ(t) at t= 0.1, 0.2, 0.3, and 0.4. Enclose arguments of functions in parentheses. For example, sin(2x).
