Whenever I write equations in an align they end up very messed up. I have attached picture of how they look. How do I get the equations to start at the left and not suddenly to the right? My align environment says: \langle x^2 \rangle = \int_{-\infty}^{\infty}e^{-\mid...

Hello everyone, In the past few days, I have learned quite a bit of basic Latex. Thank you all for the tips. Now for the question: do macs automatically come with a latex typesetter (I think that this is the case), and if so, how do I use it? Right now, I'm just going to use this post to copy...

Hi, I'm trying to write some equations in LaTeX. They are inside an align environment. My code is the following: \begin{align*} \omega_\mu{}^{ab}(e) &= \frac{1}{2} \eta^{ac} \eta^{bd} e^\nu_c e^\rho_d ( \Omega_{[\mu \nu] \rho} - \Omega_{[\nu \rho] \mu} + \Omega_{[\rho \mu] \nu}) \\ &=...

Hi guys, I'm totally new to latex and I'm loving it so far :) Quick question: when I use "\begin{align}" & "\end{align}" for a system of equations, I get them all aligned up at the "=" signs (assuming I place a "&" in front of them). Is there a way to get them all aligned vertically at the...
