Some previous research experience and additional qualifications may be given The postal address to send the application is Senior Administrative Officer (R & D Office), IRCC Wing, SJMSOM Building, Indian Institute of Technology Bombay, Powai, Mumbai- 400076. Knowledge of C-programming and numerical algorithms relevant for scientific computation (eg: solving differential equations, matrices etc.) iii). Equations = { x0: 2*x0 + cos(3*x0), x1: sin(x0+x1) }. To get a numerical solution of a differential equation, the first step is to replace the continuous domain by a lattice and the differential operators with their discrete versions. Finally, Solving for P, the amount we pay each period, we get: P = rA / (1 – (1 + r)^(-N)). StartPoint = {x0: 3, x1: 2} timeArray = arange(0, 1, 0.01) myODE = ode(equations, startPoint, timeArray) r = myODE.solve() print(r.msg). Where the amplitude R and the phase φ are determined by the initial conditions. That is, we all u(t) = R cos(ω0t – φ). I checked this formula against We can also use a differential equation to get a very close approximation of the payments on a mortgage. So, RS = R + R^2 + … + R^(N-1) + R^N Subtracting: S – RS = 1 – R^N, and so S = (1 – R^N) / (1 – R) Inserting this value for S back into Equation 1: A(1 + r)^N – P( (1 – R^N) / (1 – R) ) = 0. The general solution to a non-homogeneous linear differential equation is the general solution to the corresponding homogeneous equation plus any particular solution to the non-homogeneous equation.
