WebNumerically Solve Equations. When the solve function cannot symbolically solve an equation, it tries to find a numeric solution using the vpasolve function. The vpasolve function returns the first solution found. Try solving the following equation. The solve function returns a numeric solution because it cannot find a symbolic solution. WebThen rewriting the differential equation into: t 3 y ( 3) = − a x 3 − 6 x 2 − b x 1 + c u Usually the left hand side of the equation would be simply x ˙ 3, but here it isn't. So what I did was calculating x ˙ 3 from x 3 = t 2 y ¨, which yields x ˙ 3 = 2 t y ¨ + t 2 y ( 3). Now I want that to be equal to t 3 y ( 3).
