problem with \begin{align}

Post by rayman »

Hello! I am having some problems with setting up a nice equation with \begin{align*}. This is the equation

Code: Select all

\begin{align*}\int\limits_{P}\alpha(x,y)=\int\limits_{0}^{1}\alpha(t,t^2)\\
= \int\limits_{0}^{1}[2dt+3td(t^2)]\\
= \int\limits_{0}^{1} (2+6t^2)dt\\
= 4 \end{align*}
But it does not look nice. I would like this to look like that (please see the attachment) and it should not be numbered

Thank you!

Hi,

use the ampersand & to mark the place for the alignment:

Code: Select all

\begin{align*}
  \int\limits_{P}\alpha(x,y) &= \int\limits_{0}^{1}\alpha(t,t^2)\\
  &= \int\limits_{0}^{1}[2dt+3td(t^2)]\\
  &= \int\limits_{0}^{1} (2+6t^2)dt\\
  &= 4
\end{align*}
Btw. the forum has a code environment which makes LaTeX code more readable. You can click the Code button above the edit field when writing or editing. I just did that for you.
