DSolveValue

DSolveValue[eqn, expr, x] gives the value of expr determined by a symbolic solution to the differential equation.

Examples

Solve ODE and get function:

DSolveValue[{y'[x] == y[x], y[0] == 1}, y[x], x]
(* E^x *)

Second order ODE:

DSolveValue[y''[x] + y[x] == 0, y[x], x]
(* C[1] Cos[x] + C[2] Sin[x] *)
