# Topic for a math talk [closed]

I have to make a talk about mathematics for first and second year undergraduate students of maths. If someone could help me with a topic or an idea, it would be helpful.

Preferably it is something motivational or curious that need analysis or basic things of algebra. For example, I found the problem of monkeys and Shakespeare novels. Things like that, I'm looking for.

• How about taking the $i$th derivative of something using fractional calculus: math.stackexchange.com/q/705230/104041 ? Here $i^2=-1$. – Shaun Sep 7 '19 at 23:15
