(Shamelessly stolen from mathoverflow)

Let $\int f = \int_0^x f(u) du$

Solve

$\int f = f - 1$.

Solution:

factor out the f from the integral

$f \int = f - 1$

Re-arrange:

$f = \frac{1}{1 - \int}$

expand the right in a geometric series

$f = 1 + \int_0^x + (\int_0^x)^2 + \dots$

$f = 1 + \int_0^x + \int_0^x( \int_0^x dx) dx + \dots$

$f = 1 + x + x^2/2 + \dots$

$f = e^x$

Not quite a joke but it happened and I thought it was funy.

A few months back my nephew came in on Friday evening and was all chuffed with himself - he got 10 out of 10 in a spelling test.

The next Friday he came in and his mum asked him how he did in his weekely spelling test. "I didn't do as well this week - i only got 8 out of 8"

Normally only takes me a few secs.

If you look at 3.14 (pi) in the mirror, it looks kindof like PI.E!!
I don't have a picture of it though.:(

Some say a world without sin is ideal, but I disagree. After all, there's only so many problems which can be answered with cos and tan.

At least your nephew is a child....

My dad used to work as a polling station supervisor during the General Elections. One year (this would have been in the 90s), one of the prospective candidates came up to him as the evening was drawing to a close. The candidate asked how the turnout had been.

''Oh excellent'' replied Dad ''We're almost up to a hundred and ten per cent.''

''God, that's great'' said the candidate and away he went. He was subsequently elected and went on to become a Junior Minister :rolleyes:
