this is entirely correct; very thorough too :3

also this should entirely be accessible to anyone who’s done just enough calculus to talk about maxima and minima of continuously differentiable functions, which means either high school or undergrad calc, depending on your educational path; don’t be so worried ;p

(incidentally you could have skipped from h=l/√3 straight to the answer by using arccos instead of arctan but arctan is a nicer function anyways so w/e)
