Consider the initial value problem below to answer to following. a) Find the approximations to y(0.3) and y(0.6) using Euler's method with time steps of At 0.3, 0.15, 0.075, and 0.0375 b) Using the exact solution given, compute the errors in the Euler approximations at t 0.3 and t 0.6. c) Which time step results in the more accurate approximation? Explain your observations. d) In general, how does halving the time step affect the error at t 0.3 and t...

6. (a) Newton's method for approximating a root of an equation f(x) 0 (see Section 3.8) can be adapted to approximating a solution of a system of equations f(x, y) 0 and gx, y) 0. The surfaces z f(x, y) and z g(x, y) intersect in a curve that intersects the xy-plane at the point (r, s), which is the solution of the system. If an initial approxi- mation (xi, yı) is close to this point, then the tangent planes...
