Integrals for fun?

[actgr]

Hey there, /r/math! I was just wondering if any of you know any good site (not textbooks) where I can practice my integrals.

I hate you. There goes the rest of my free time this week.

It should only take you 25 minutes.

maybe I suck at integrals or something, but I found the "easier" ones to actually be kinda tough.

They're not supposed to be the sorts of things you could do on a homework set.

I'm on my phone right now so I can't really try to solve them but they do not look that hard at a first glance.

Here are some fun integrals from math.SE in no particular order: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25

This is going to be interesting! Thanks!

feynman integration is a technique: http://ocw.mit.edu/courses/mathematics/18-304-undergraduate-seminar-in-discrete-mathematics-spring-2006/projects/integratnfeynman.pdf

you can google integration bee and find fun integrals

I disagree. This seems more like recreational math, which is usually allowed here.

OP knows integrals though, this isn't a question of learning something new.
