πŸ”₯ Day 152 β€” 2026 MIT Integration Bee (Qualifying) Q18 365 Problems for 365 Days Evaluate: Integral of (sin^2(x)/x^2 βˆ’ sin(2x)/x) dx This one is a β€œrecognize the derivative” speed problem. The integrand looks messy, but it’s literally the derivative of a super simple expression if you think β€œquotient rule trig identity.” If you try to integrate directly, it’s pain. If you spot the structure, it’s instant. Hints: \tβ€’\tLook for something like (sin^2 x)/x \tβ€’\tDifferentiate it with the quotient rul

πŸ”₯ Day 133 β€” 2025 MIT Integration Bee (Qualifying) Q17 Evaluate: ∫ sin(x) * sinh(x) dx Wild mix of circular and hyperbolic functions. The fastest path is a classic double β€œintegration by parts” loop: set up I = ∫ sin(x) sinh(x) dx, integrate by parts twice, and watch I appear on both sides so you can solve for it. πŸ‘‰ Hints β€’ First parts: u = sin x, dv = sinh x dx. β€’ Second parts (on the new integral): u = cos x, dv = cosh x dx. β€’ You’ll end with 2I = (sin x) cosh x βˆ’ (cos x) sinh x.

πŸ”₯ Day 125 β€” 2025 MIT Integration Bee (Qualifying) Q8 Evaluate: Integral from 1 to 2 of [ 2^(xβˆ’1) log_2(2x) ] dx This one is cleaner than it looks. Split the integral into two parts, turn log_2(2x) into 1 (ln x)/(ln 2), and remember the antiderivative of a^x. If you keep the algebra tidy, everything telescopes to a surprisingly neat number. πŸ‘‰ Hints β€’ ∫ 2^(xβˆ’1) dx = 2^(xβˆ’1) / ln 2. β€’ log_2(2x) = 1 (ln x)/(ln 2). β€’ ∫ ln x dx = x ln x βˆ’ x. Would you spot the simplifications under time pressure? ⏱️

πŸ”₯ Day 121 β€” 2025 MIT Integration Bee (Qualifying) Q4 Evaluate: Integral from 1 to e^e of [ log( x^(log(x^x)) ) / x^2 ] dx Looks wild, but the trick is to simplify before integrating. If you collapse the nested powers/logs the integrand turns into something that begs for a one-line u-sub. πŸ‘‰ Hints β€’ Use: log(a^b) = blog(a) and log(x^x) = xlog(x). β€’ You should get (log x)^2 / x, then let u = log x.
