For those of you familiar with Robert Penner’s easing equations, do you feel any shame using them? I mean, do you think that people who use Penner’s formulas are unoriginal and such?

I like the equations, but I don’t like taking someone else’s code and using it (with credit of course)…but then again, I don’t have the math skills just yet to create my own formulas…hm. So, does anyone see anything wrong with using Penner’s (or anyone else’s) equations?
