Hello fellow Wikipedians,

I have just added archive links to 1 one external link on Forcing function (differential equations). Please take a moment to review my edit. If necessary, add after the link to keep me from modifying it. Alternatively, you can add to keep me off the page altogether. I made the following changes:

Suggestion: say "f(t)" instead of "f(x)"
In the current or "latest" version (the "22:14, 1 August 2021‎" version) or "revision" of this article, the first paragraph says"In a system of differential equations used to describe a time-dependent process, a forcing function is a function that appears in the equations and is only a function of time, and not of any of the other variables.[1][2] In effect, it is a constant for each value of t."now.

So IMHO, in the last paragraph, it should probably say "f(t)" instead of "f(x)". (two places). (right?)

This is not a big deal. For one thing, technically one can say "f(x)" when f [QUOTE:] "is only a function of time". That is, "x" could be -- [or, it could "indicate"] -- time.

However, I think that it might be less confusing to say "f(t)". It would be more consistent with the first paragraph (the one above).

Any comments? --Mike Schwartz (talk) 21:13, 20 January 2022 (UTC)


 * Agree that f(t) would cause less confusion and be more consistent. Universemaster1 (talk) 17:31, 2 February 2022 (UTC)


 * Thank you for that reply comment, and thank you for making this edit. (However, now it seems that ... about one day later ... your "User:" page and your "Talk:" page are both showing up as dead links; [see red link, e.g.]. I am not sure why "that" happened ... maybe it is outside the scope of [this section of] this "Talk:" page ...) Rock on...
