Please take a look around and make yourself at home!
We at Calculus Humor thought it would be fun to host a costume contest. This contest is open to everyone. There are no entry fees (and as an effect, there are no prizes) Please fill out this form below and have fun!
We will not be posting a Problem from heck this week as we need to take a break. We will have one next week so be ready!
Do you want to email us? We have a new email address, [email protected] for those who wish to contact us.
We posted "How to Prove It: Guide for Lecturers" way back in August. Now it is time to revisit it and play "How to Prove It: Guide for Lecturers Bingo!"
How to play:
Before each math class, visit How to Prove It: Guide for Lecturers Bingo and print one copy of this game card for each player, refreshing the page before each print, or have the players print their own bingo cards. These instructions will not be printed. You can also select card only and multiple card versions of this page when playing online, or with a PDA.
Check off each block when you hear these words during the class. When you get five blocks horizontally, vertically, or diagonally, stand up and shout "EUREKA!!!".
Need to refresh what the definitions are? Then visit http://www.calculushumor.com/3/post/2012/08/how-to-prove-it-guide-for-lecturers.html.
A Colombian drug lord plans to bribe some police officers so that they will let his cocaine pass the boundary freely. He knows that the more officers he bribes, the more cocaine he can transfer. Let the fraction of bought officers be xϵ[0,1] and let f(x)ϵ[0,1] be the fraction of the total cocaine harvest not intercepted.
Naturally the function f is increasing and f(1) = 1. Indeed, if the whole police is bought than nothing prevents the cocaine from crossing the border.
Suppose that the cocaine is C£ worth and the whole police costs P£. Calculate the maximal income and find out how much police the drug lord should bribe if
Why is π in this formula? Well the cocaine grew on a round field.
This started as a way to express the admins' love of calculus and math in general. As result, this has turned into a gathering place for math-based humor and weekly challenges.
