Nov 23, 2023 at 19:23 | comment | added | mathematrucker | When our Putnam prof was prepping us for the 1981 exam (he wasn't involved with its creation), he said "it always has a Lagrange multiplier problem." Luckily for me, his prediction came true:$$$$$\textbf{B-2.}$ Determine the minimum value of $$(r-1)^2 + \left(\frac{s}{r} - 1\right)^2 + \left(\frac{t}{s} - 1\right)^2 + \left(\frac{4}{t} - 1\right)^2$$ for all real numbers $r,s,t$ with $1\leq r\leq s\leq t\leq4.$$$$$ Fewer than 2% of contestants got a perfect $10$ on the problem. Thanks to my professor's prescience, I was one of them. | |
