In summary: On the surface this one looks a bit ... disconnected.It's the fundamental theorem of calculus. On the left hand side, you have the integral (area) under the curve f(x) from a to b. On the right hand side, you have the difference between the values of the antiderivative F(x) at a and b. So it's connecting the concepts of area and slope (antiderivative).

Tooltip: "So what do we do when we get to base 10? Do we use A, B, C, etc? No: Numbers larger than about 3.6 million are simply illegal."

What do you get if you cross a mountain climber with a mosquito?
Nothing, you can't cross a scalar with a vector.

Oh, my. ... Based on that, I just made this one up.
What do you get when you cross a rotten apple with an angry baboon?
What do you get when you cross a rotten apple with an angry baboon?
Apple: [itex] \vec a [/itex]
Baboon: [itex] \vec b [/itex]
[tex]
\vec a \times \vec b =
\begin{vmatrix}
\hat x & \hat y & \hat z \\
a_x & a_y & a_z \\
b_x & b_y & b_z \\
\end{vmatrix}
= (a_y b_z - a_z b_y) \hat x + (a_z b_x - a_x b_z) \hat y + (a_x b_y - a_y b_x) \hat z
[/tex]
Baboon: [itex] \vec b [/itex]
[tex]
\vec a \times \vec b =
\begin{vmatrix}
\hat x & \hat y & \hat z \\
a_x & a_y & a_z \\
b_x & b_y & b_z \\
\end{vmatrix}
= (a_y b_z - a_z b_y) \hat x + (a_z b_x - a_x b_z) \hat y + (a_x b_y - a_y b_x) \hat z

Apologies for being a downer here, but this one's better if you actually write out the numbers: "There are 10 kinds of ..."nuuskur said:

Unfortunately sin(pi e) =~ 0.774. You need to eat 1/e of a pi e.
