A quadratic equation is generally represented as, ax^2 + bx + c The root(s) of the above quadratic equation is computed using the following formula, root1 = (-b + sqrt(D))/ 2a root2 = (-b - sqrt(D))/2a Where D is the discriminant of the quadratic equation and is computed as, D = b^2 - 4ac Given the value of D, the roots of a quadratic equation can be categorized as follows, D > 0 : Two distinct real roots D =...
Obtain a rough estimate of all real roots of the function f(x) = ex-x-2 by incremental searching in [-2,2]. Use Ax- 1. b) Obtain two iterating functions for finding each of these roots by fixed-point iteration by solving for each x which appears in the equation. c) Without doing any iterations, determine if each iterating function will converge to each root and ether the convergence or divergence will be monotonic or oscillatory [25] a) 1. d) From the iterati ng...

Given: y''+2y'=2x+5-e^-2x General solution is: y=c1e^-2x+c2 +1/2(x^2)+2x+1/2(xe^-2x) Solve using the method of undetermined coefficients and show all steps please! I have the form of yp is Ax^2+Bx+Cxe^-2x, and the issue that plagues me is in solving for A B C. I get A=1/2 and I get B=2, but the terms involving C fall off the face of the earth when I substitute y' and y'' of the solution form into the equation, so how can I solve for C? Help...
pls answer this fast 2. (a,b) is a random point in square 0 = {x,y):-15:51, -Isysl} Find the probability that equation AY + x = 0 has two real roots.
please answer compleltly 2. Find the eigenfunctions and eigenvalues for the differential equation d^2u(x)/dr^2 = -k^2 u(x) in the interval 0 < = x < = a, assuming k is a real number, for the following sets of boundary conditions: (a) bu(0)+cdu/dt|x=0 =0 and bu(a)+cdu/dx|x=a =0 (b) u(0)+a du/dx|x=0 =0 and u(a)-adu/dx|x=a =0 You need not normalize the eigenfunctions. For (b), find the equation which determines the eigenvalues and verify that there is an infinite set of eigenfunctions and eigenvalues;...
