Now, to take the derivative, we need the quotient formula: if y=u/v,

dy/dx = (v du/dx - u dv/dx)/v^2

See, that right there.....the quotient formula for differentiation is something I haven't used - or even seen - in over 20 years. I recognized it immediately when I read your post, but there is no way I was going to remember that on my own. I could have researched it, but I was that not that grossly into solving the equation that I would have found that.

I very much still have my math aptitude and creative solving abilities, but to remember very specific calculus equations is not something in me now.
