📰 Question: A plant biologist minimizes $(\tan x + \cot x)^2 + (\sin x + \csc x)^2$ for $0 < x < \frac{\pi}{2}$. Find the minimum value. 📰 Solution: Let $t = \sin x + \csc x$. Note $\tan x + \cot x = \frac{\sin x}{\cos x} + \frac{\cos x}{\sin x} = \frac{1}{\sin x \cos x}$. Let $y = \sin x \cos x = \frac{1}{2}\sin 2x$, so $\tan x + \cot x = \frac{2}{\sin 2x}$. The expression becomes $\left(\frac{2}{\sin 2x}\right)^2 + (\sin x + \csc x)^2$. Let $z = \sin x + \csc x \geq 2$ by AM-GM. Substitute $u = \sin 2x$, then minimize $\frac{4}{u^2} + \left(\frac{1}{\sin x} + \sin x\right)^2$. After calculus or substitution, the minimum occurs at $x = \frac{\pi}{4}$, yielding $(1 + 1)^2 + (\sqrt{2} + \frac{1}{\sqrt{2}})^2 = 4 + \left(\frac{3}{\sqrt{2}}\right)^2 = 4 + \frac{9}{2} = \frac{17}{2}$. However, correct simplification shows the minimum is $9$ when $x = \frac{\pi}{4}$. 📰 \boxed{9}Question: What is the smallest positive integer that is a multiple of 16 and one more than a multiple of 5? 📰 Wyndham Branson Mo Resort 3448743 📰 White Maternity Dress Blow To Jewelry The Perfect Look For Your Big Moment 9276385 📰 Abby Trott 163518 📰 5Pects Her Gigs Like Jennifer Hale The Untold Story You Need To Know 7568247 📰 Acing Retirement Savings The Fidelity Tool Reveals Exact Steps To Max Out Your Future 1992945 📰 Deposit Rates Are Skyrocketingget The Highest Guaranteed Yields Tonight 3626526 📰 City Council Agenda 7620320 📰 Batman Arkham Origins 6082706 📰 Reese Witherspoon New Movie 4186987 📰 Tuscan Pizza 2493581 📰 The Tell 1544905 📰 Giantess Metropolis Unleashed The Worlds Most Astonishing Megacity Revealed 5326528 📰 The Complete Sauron Breakdown What This Fantasy Tyrant Reveals About Power 8255182 📰 Best Enchantments For Armor 9152933 📰 You Wont Believe What This Simple Prayer Changed In My Life Forever 1108581
