so you want a VERY HARD math question?! @blackpenredpen

blackpenredpen | so you want a VERY HARD math question?! @blackpenredpen | Uploaded 2 years ago | Updated 6 hours ago
Can you solve this very very hard math equation? I would say 99% of the student population won't be able to solve it! We need to find x so that the integral of x^t from 0 to 2 is equal to 3. Not only do we need to know how to integrate a basic exponential function, but we also need to use the Lambert W function (with a technical part) for this integral equation. To make this more fun, I did NOT edit the video! I think this integral equation might be the equation of the year! Enjoy!
