See attached file for full problem description. f = r.k/|r^3| What is the gradient of f? Show that for vectors v and r and constant vector a we get: if v=(a.r)r Div(v) = 4(a.r) Curl(v) = a x r
16. Let P_2(x) be the quadratic polynomial interpolating f(x) at the evenly space point x_0, x_1 = x_0 + h, x_2 = x_0 + 2h. Derive formulas for the error: f'(x_i) - P'_2(x_i), i = not zero, 1, 2 Assume f(x) is three times continuously differentiable, give commutable bounds for these errors. Hint: use the error formula
For all real number a & b, if a<b then a^2<b^2 (a squared is less than b squared)
I need to solve a system of vector loop equations, using the Newton-Raphson method and find the (x,y) coordinates of the coupler point. This problem (NEW ATTACHMENT) is listed in "Applied Numerical Methods for Engineers and Scientists" by Singiresu S. Rao: problem 2.3, page 139.
(i) Use the tabulated data and Newton's method of divided differences to (a) calculate the degree three interpolating polynomial based on x_0, x_1, x_2, x_3 and (b) calculate the degree four interpolating polynomial based on x_0, x_1, x_2, x_3, x_4. x_k || 0 | -1 | 1 | 3 | 2 y_k || 5 | 15 | 3 | 47 | 9 (Use exact arithmeti
