the equations. In general, the safest method for solving a problem is to use the Lagrangian method and then double-check things with F = ma and/or ¿ = dL=dt if you can. | At this point it seems to be personal preference, and all academic, whether you use the Lagrangian method or the F = ma method. The two methods produce the same equations. The method of substitution in integration is similar to finding the derivative of function of function in differentiation.
