I have some math structured like the following in a display math environment:  \left( \frac{ \left( \frac{a}{b} \right)^{e} }{L} \right)     Apparently, the outer fraction is centered vertically in the surrounding parentheses even though its numerator requires more space than the denominator L.  To me this looks unbalanced with too much space below the L.  Is there a way of shifting the entire content of the outer parentheses down?   MWE:  \documentclass[]{standalone} \usepackage[utf8]{inputenc} \usepackage{amsmath} \begin{document}     $\displaystyle         \left( \frac{ \left( \frac{a}{b} \right)^{e} }{L} \right)     $ \end{document}
Have a look at the following code:  \documentclass[letterpaper]{article} \usepackage{amsmath,amssymb} \begin{document}  $2-\frac{2}{1-\left(\frac{2}{2-\frac{2}{x^2}}\right)}$\quad  $2-\dfrac{2}{1-\left(\dfrac{2}{2-\dfrac{2}{x^2}}\right)}$\quad  $2-\cfrac{2}{1-\left(\cfrac{2}{2-\cfrac{2}{x^2}}\right)}$\quad  $2-\dfrac{2}{1-\left(\cfrac{2}{2-\dfrac{2}{x^2}}\right)}$ \end{document}   This gives:    Evidently, the first display is not the proper way. The second and last are the same I guess. The third has a better display but there is too much space above the 2 in \left(\cfrac{2}{2-\cfrac{2}{x^2}}\right). Essentially, non of the above displays satisfies, for me, a good Mathematical typsetting. Although, it may be argued that it is the default in LaTeX. I just can't get it right? Any insights? In a book I got this example from it looks like this without the excessive bold (this is a scanned image):

Why can't I use a type argument in a type parameter with multiple bounds? I'm trying to solve    So far I've done the first part, evaluating the summation ;  where a is just n. I'm not sure where to go from here or what it even means deduce the second summation. I understand that the summation of simply $$\sum\limits_{k=0}^n\cos(kx)$$ is derived from looking at the real part of  $$\sum_{k=0}^n{\rm e}^{ikx} $$I'm guessing they want me to see how the second summation in the question is defined by 'playing around' with the original? Will getting a Software Testing Certification benefit me in my career? I have 2 years of experience in manual testing, and I am currently learning automation testing in my spare time. I was thinking that will getting a foundation/entry testing certification really help me in promotions and increase my salary or just increase my knowledge and nothing more? Even if I wish to try to get certified and pass the exams, is it too late or can I try after a few more years?  Kindly suggest! What should the standard spelling be - British or US? I just saw someone edit the title of  question to  the spelling from favourite (The British spelling) to favorite (The US-English spelling).  Does SOFU have an accepted standard on language and spelling? Which is it? Background Video is shown in Rendered mode but not when szene is rendered Can Debian identify rarely used packages? I'd like to find a tool that could tell me which Debian packages on my system have been rarely or never used, perhaps by looking at file lists and access times.  This is to find candidates for deletion from my nearly full hard drive.  I'm not very well informed about the rich ecosystem of desktop GUI tools (I use aptitude); does anyone know if one of those tools, or any other tool, can identify how recently a package has been used? Can't install/uninstall packages in Debian I'm trying to install/uninstall packages in Debian but getting errors.    I can't remove or add any package, always getting the error.   I tried:  apt-get --remove purge package apg-get remove package dpkg -r package distribution with point support Does the alarm work when my phone is turned off? Will the alarm still go off if I turn off the phone before?  Example: when I have low battery, I have to go to sleep and wake up at X o'clock, and there is no charger around. Should I turn off the phone?   Note: If it makes any difference my phone is Galaxy S running froyo How to prove $n^5 - n$ is divisible by $30$ without reduction How can I prove that prove $n^5 - n$ is divisible by $30$? I took $n^5 - n$ and got $n(n-1)(n+1)(n^2+1)$ Now, $n(n-1)(n+1)$ is divisible by $6$. Next I need to show that $n(n-1)(n+1)(n^2+1)$ is divisible by $5$. My guess is using Fermat's little theorem but I don't know how. Deploy Community Builder audience page assignments with ant migration tool? What is the best way to go about calling a function given a string with the function's name in a Python program.  For example, let's say that I have a module foo, and I have a string whose content is "bar". What is the best way to call foo.bar()?  I need to get the return value of the function, which is why I don't just use eval. I figured out how to do it by using eval to define a temp function that returns the result of that function call, but I'm hoping that there is a more elegant way to do this. How does the coin limit work? The new gym update , including a limit of 50 coins earned per day. How does this limit work? Is each pokemon limited to accruing 50 coins per day? Are all my pokemon limited to a collective 50 per day? My teammates keep feeding my Dragonite and she has been at the gym for almost a week; will she return with 50 coins for each day she was there? Fewer than 50 for the days I had other pokemon in the gym? Or will she accumulate vast sums of coins over the week, but only deliver me 50 (or fewer) when she comes back based on what I have collected from returning pokemon that day? I have a sqlite (v3) table with this column definition:  "timestamp" DATETIME DEFAULT CURRENT_TIMESTAMP   The server that this database lives on is in the CST time zone.  When I insert into my table without including the timestamp column, sqlite automatically populates that field with the current timestamp in GMT, not CST.  Is there a way to modify my insert statement to force the stored timestamp to be in CST?  On the other hand, it is probably better to store it in GMT (in case the database gets moved to a different timezone, for example), so is there a way I can modify my select SQL to convert the stored timestamp to CST when I extract it from the table? What is the correct way to create a single-instance WPF application? For some reasons my brush stroke suddenly looks like this:     As the picture showed, the edges are jagged and pixelated. It doesn't happen before and it's just one of the built-in inking brush.  I know there are a lot of similar questions here but please don't mark this as duplicate. I double checked all the thing the other answers suggested: It's brush tool, not pencil, and my mode of brush and layer is Normal, not Dissolve. It's pixelated even if I draw with mouse so it's not tablet driver issue. I disabled GPU render but nothing changed. How do I fix this? Positive operator is bounded For a real Banach space $X$ let $A:X\rightarrow X^*$ be a positive operator in the sense that $(Ax)(x)\geq 0$ for all $x\in X$. Show that $A$ is bounded.   I don't know how to do that, maybe it's an application of the closed graph theorem?
