Is this IMPOSSIBLE???

I misjudged this one at first

Don't panic! This one is not that bad :)

is this INSANE???

Surprisingly quick & easy! :)

Does it converge???

It's Lambert W time! (with some cheating)

A slightly alternative method

OVERKILL every series you find

Yep we got a determinant in the integral!

The secret trick your teacher doesn't want you to know 🤣

very CLEVER integral!!!

No good method exists???

I sometimes worry that Feynman's trick is too powerful

This one is tricky!!! 😵‍💫😵‍💫

I decided NOT to do an integral!😮😮😮

Can I use Weierstrass on this one????

Challenging integral!! (featuring the Wallis Product)

Let's make use of THE GAMMA FUNCTION :)

"The simplest Differential Equation in the world."

Berkeley Math Tournament 2023 Tie Breaker #2

Hint: sometimes the floor / ceiling turn integrals into series :)

QUICK Integral! JEE Main 2003

Almost King's Principle???

I FAILED to fully explain this one.

NO Gamma Function allowed!!!

The first step is the most important!

I know 3 methods and they're ALL THE SAME :)
