Solve a xSol = 3 ySol = 1 This will help to determine the functions used in MATLAB for finding the solution of system of equation. I am trying to solve a projectile motion problem, to determine the take off velocity under given initial conditions, the problem was reduced to a system of two second order differential equations. First of all, we can define the variables using the syms variable. To find these solutions numerically, generally used function is vpasolve. I know that this would usually 9x-3y=-1 (1/5)x+(2/5)y=(-1/3) Range y=x= +-5. However, because of dependency, in fact I have 5 eqs. Solve a differential equation analytically by using the dsolve function, with or without initial conditions. 2.
