- Q.2 Solve x/1+ y² + yv1+x² = 0. dxarrow_forwardI am in a hurry, I need the answer as soon as possible, please help.arrow_forward3. (a) By sketching the graphs of 1 y = In x and y = x2 on the same coordinate system, determine the number of solutions of the equation In x = 2. et-2 has a unique fixed-point in the (b) Show that the function g(x) = interval [1.5, 2]. %3D (c) Use part (i) and (ii) to carry out three iterations to approximate the root of In x =2, starting with po = 1.5.arrow_forward
- Find all solutions of the form y = erx for the equation y''−y'−2y = 0. Then write the most general solution that can be made out of them.arrow_forward2. An initial value problem and its exact solution y(x) are given below. Apply Euler's meu twice to approximate to this solution on the interval [0, ½], first with step size h = 0 25 (two steps), then with step size h = 0.1 (five steps). Compare the three-decimal-place values of the two approximations at x = 2 with the value y(½) of the actual solution. y' =(1+y?),y(0) = 1; y(x) : = tan (x + T) "ехact" approx. h f(xn, Yn) Yn+1 Xn+1 f(xn Yn) in Yn Yn+1 1 1 4arrow_forwardA hand-held calculator will suffice for Problems 1 through 10, where an initial value problem and its exact solution are given. Apply the improved Euler method to approximate this solution on the interval [0, 0.5] with step size h = 0.1. Construct a table showing four-decimal-place values of the approximate solution and actual solution at the points a = 0.1, 0.2, 0.3, 0.4, 0.5. y' = -3x²y, y(0) = 3; y(x) = 3e-² Answer Note: In Problems 2 through 10, we give the value of x, the corresponding improved Euler value of y, and the true value of y. 0.5, 2.6405, 2.6475arrow_forward
