I'm using the natbib package with the agsm bibliographic style to generate and use the bibliography in a report.   But whenever I cite an article having many authors, the layout in the document is 'Author et al.'   Which command can I use to have the following result: 'Author. F et al.', i.e. to italicize 'et al.'?
I am using natbib and agsm for harvard-style referencing. My related code is  \usepackage{natbib} \bibliographystyle{agsm}   Then I am using \citep{} for citations. My problem is that in text I am getting     (Author et al. 2012)   but and I want     (Author et al. 2012)   Does anyone know how to change this and get 'et al' in italics in the text?  I am using TexPad and BibDesk and I have not been able to find the .bst files in Terminal.  I know that it is often correct to have the 'et al.' unitalicised but my university regulations requires italics.
Is the Schrödinger equation derived or postulated? I'm an undergraduate mathematics student trying to understand some quantum mechanics, but I'm having a hard time understanding what is the status of the Schrödinger equation.  In some places I've read that it's just a postulate. At least, that's how I interpret e.g. the following quote:     Where did we get that (equation) from? Nowhere. It is not possible to derive it from anything you know. It came out of the mind of Schrödinger.    -- Richard Feynman   (from the Wikipedia entry on the Schrödinger equation)  However, some places seem to derive the Schrödinger equation: just search for "derivation of Schrödinger equation" in google.  This motivates the question in the title: Is the Schrödinger equation derived or postulated? If it is derived, then just how is it derived, and from what principles? If it is postulated, then it surely came out of somewhere. Something like "in these special cases it can be derived, and then we postulate it works in general". Or maybe not?  Thanks in advance, and please bear with my physical ignorance. Indefinite integral of secant cubed I need to calculate the following indefinite integral:  $$I=\int \frac{1}{\cos^3(x)}dx$$  I know what the result is (from Mathematica):  $$I=\tanh^{-1}(\tan(x/2))+(1/2)\sec(x)\tan(x)$$  but I don't know how to integrate it myself. I have been trying some substitutions to no avail.   Equivalently, I need to know how to compute:  $$I=\int \sqrt{1+z^2}dz$$  which follows after making the change of variables $z=\tan x$. In the magical world (in Harry Potter) can ghosts use magic?  Can magic be used on ghosts?  Or, once they become ghosts, can they interact with magic at all? Equation number enclosing parentheses misplaced with Polyglossia+Hebrew+amsmath Modify a shape and have modifications apply to clones Is there any any "Symmetry Modifier" option in illustrator?   Let's say I want to create a head that is totally symmetric. I created one half then mirrored it to get another half. Flipped the other half, aligned them and joined them together with Pathfinder→Unite option.   Now I modified some portion of the right half outline. But how can I get that same modification to be updated on the left option? I thought it would happen automatically. What exactly are DLL files, and how do they work? How exactly do DLL files work? There seems to be an awful lot of them, but I don't know what they are or how they work.  So, what's the deal with them? Can I register a domain name that contains a company name or trademark? I wonder is it legal to register a domain name that contains a company name. For example cococola.cc (considering that this domain name is available). Can I buy and use any domain names that contain a name of a trademark? When is the Killing form null? What is ETTR (Expose To The Right)? What's the keyboard shortcut for keyboard layout switch in Mojave? Shift + Control + Space doesn't seem to work anymore.

Prove $\chi(G)\chi(\bar{G}) \geq n$ for chromatic number of graph and its complement Volume of the torus with an integral Inverse of a Positive Definite Vertical text (not in table) Word for "blissfully oblivious"? Why cast an unused function parameter value to void? How do you check if a JavaScript Object is a DOM Object? I'm trying to get:  document.createElement('div')  //=&gt; true {tagName: 'foobar something'}  //=&gt; false   In my own scripts, I used to just use this since I never needed tagName as a property:  if (!object.tagName) throw ...;   So for the second object, I came up with the following as a quick solution -- which mostly works. ;)  The problem is, it depends on browsers enforcing read-only properties, which not all do.  function isDOM(obj) {   var tag = obj.tagName;   try {     obj.tagName = '';  // Read-only for DOM, should throw exception     obj.tagName = tag; // Restore for normal objects     return false;   } catch (e) {     return true;   } }   Is there a good substitute? $f(x)=x/1$ is not injective?
