so you want a HARD integral from the Berkeley Math Tournament
You can now register for BMT 2022 here: The firstplace team wins 1000 bprp scholarship and I will be there We will integrate x, tan(x) from 0 to pi, 2. We will use Feynman s technique (aka Feynman s trick of integration or differentiation under the integral sign) to compute this integral. This problem is from the Berkeley Math Tournament in 2020. Here s the link to the exam and the solution: If you are also interested in sponsoring BMT and making an impact, please contact Thank you 0:00 we haven t done a hard integral for a while 2:33 the steps of Feynman s trick of integral 5:30 differentiate I(a) first, then do the integral 18:59 integrate I (a) with respect to a to get I(a) Shop math tshirts hoodies: 10 off with the code WELCOME10
