\end{align}

</math>

In the first example, three consecutive dots were typed, but the second example uses LaTeX's \cdots command.  This stands for 'center dots'.  There are also other 'dot' functions.

Hello, this is gary from ma181.  let's solve the extra credit problem.

*So what does this equation "E < M(b-a)^2/N" mean.  This reads that the error is less than the Maximum value of the derivative of the function of x multiplied by the interval squared from x=a to x=b all divided by the total number of subintervals N.

[[Homework 11_MA181Fall2008bell]]

*I don't understand why this must be true.  Maybe I'm wrong, but if f(x) were a horizontal line, wouldn't E=0 and M(b-a)^2/N also be =0.  That would mean it is a false statement that E < M(b-a)^2/N.  Are we to assume that E <= M(b-a)^2/N?

Did 'ya Know?

This week I thought that I'd demonstrate how to add ellipses in a LaTeX equation.

$ \begin{align} \sum_n &= 1 + 2 + 3 + ... + n + ... + \infty \\ &= 0 + 1 + 2 + \cdots + n + \cdots + \infty \end{align} $

In the first example, three consecutive dots were typed, but the second example uses LaTeX's \cdots command. This stands for 'center dots'. There are also other 'dot' functions.

\ldots $ \ldots $ \therefore $ \therefore $
\cdots $ \cdots $ \dagger $ \dagger $
\vdots $ \vdots $ \clubsuit $ \clubsuit $
\ddots $ \ddots $ \doteq $ \doteq $
