A cubic formula that you probably haven't seen before!
40:16
So you want to prove the cubic formula (from scratch)
22:28
so you want a HARD integral from the Berkeley Math Tournament
22:31
If I were 17, I wouldn't be able to solve this! Cambridge STEP 1 exam
18:08
a super nice functional equation
13:37
Math isn't ready to solve this problem
12:59
You probably haven't solved a quartic equation like this before!
31:27
EXTREME quintic equation! (very tiring)
