Odesolve vs rkfixed etc

What can you say about it?

From one my artice:

"Operations of dividing a second-order differential equation into two first-order ones, transferring mass from the left side of the equation to the right side, turning a set of points into a function by interpolation, and so on. in Mathcad 15, the built-in Odesolve function automatically conducts, paired with the Given keyword. This function appeared relatively recently in the Mathcad environment and is not yet available in the SMath environment. The process of solving differential equations with Odesolve can be compared to driving a car with an automatic transmission. Working with the rkfixed function and others like it is driving a car with a manual gearbox. But real car enthusiasts (almost pros) prefer a car with a manual gearbox, which allows you to drive more professionally and save fuel."

I would suggest 'to solve' is to do with understanding, while 'to fix' is to do with implementing.

For example, I have been attempting to solve (understand the cause & possible solutions for) a [medical | computer | mechanical |...] problem. Once I have solved the problem, I may be able to implement a fix for the problem using the potential solution/s I have identified. Or, I may not.
