WebSep 11, 2024 · By the method of integrating factor we obtain. exy2 = C1 2 e2x + C2 or y2 = C1 2 e2 + C2e − x. The general solution to the system is, therefore, y1 = C1ee, and y2 = C1 2 ex + C2e − x. We now solve for C1 and C2 given the initial conditions. We substitute x = 0 and find that C1 = 1 and C2 = 3 2. WebIn simultaneous coupling equations (1) are solved together, simultaneously, or at least approximately so. If (1) is linear this is done using linear matrix algebra with a matrix equation solver like Gaussian Elimination. It is implicitly realized that each y depends on the others. In sequential coupling one equation (one line of (1)) is solved and
