Consider the differential equation cos(y)y + sin(y)y = x?. (a) Is this differential equation linear? Explain why or why not. (b) If y(-2)=1, use Euler's method to estimate y(-1). Use a step size of h = 0.5. (c) What could we have done in part (b) to get a more accurate estimate? Consider the differential equation cos(y)y + sin(y)y = x?.
