Mental estimate for tangent of an angle (from $0$ to $90$ degrees) Does anyone know of a way to estimate the tangent of an angle in their head? Accuracy is not critically important, but within $5%$ percent would probably be good, 10% may be acceptable.  I can estimate sines and cosines quite well, but I consider division of/by arbitrary values to be too complex for this task. Multiplication of a few values is generally acceptable, and addition and subtraction are fine.  My angles are in degrees, and I prefer not have to mentally convert to radians, though I can if necessary. Also, all angles I'm concerned with are in the range of [0, 90 degrees].  I am also interested in estimating arc tangent under the same conditions, to within about 5-degrees would be good.  Backstory  I'm working on estimating the path of the sun across the sky. I can estimate the declination pretty easily, but now I want to estimate the amount of daylight on any given day and latitude. I've got it down to the arc cosine of the product of two tangents, but resolving the two tangents is now my sticking point. I also want to calculate the altitude of the sun for any time of day, day of the year, and latitude, which I have down to just an arc tangent. Google Sheets has several import functions   IMPORTDATA IMPORTFEED IMPORTHTML IMPORTXML   Sometimes the above functions returns errors like #N/A Imported content is empty and would like to be sure that there isn't a problem with the resource content to be imported.  How do I know if these functions are able to get the content that I looking to import?  I know that there also exist IMPORTRANGE but that function only is able to import content from Google Sheets spreadsheets Live USB data gets lost on Restart I am crawling some data using Apache Nutch and storing it on my USB Drive. The OS itself is Ubuntu Live Boot OS. But for every restart or shutdown I am losing my data. I also tried suspending my Ubuntu user still data was not visible when I reinserted my live USB.  Is there any way I can keep the data intact and does not loose and application settings installations when I do restart Ubuntu.  Used USB installer provided by pendrivelinux.com at Is there a way to change the environment variables of another process in Unix? Is there any truth to the idea that you shouldn't multiply seasonings when multiplying a recipe? I often hear cooks discuss that idea that if you are multiplying, say, a recipe for 4 to be a for 32, that you shouldn't multiply some herbs, spices, or salt. I've never understood any reason why this should be true. Maybe something to do with surface area to volume ratios, or cooking times? Does anyone have a real explanation, or is this nonsense? How to connect to device via SSH over direct ethernet connection Is there any noun in English which changes the first letter in the plural? Plenty of nouns change the second letter to become plural (man->men, goose->geese) but does anything change its first letter.  I've hunted high and low over the internet, and spent ages browsing the questions at  but I can't find anything. How to integrate $\int_0^{\infty} \frac{e^{ax} - e^{bx}}{(1 + e^{ax})(1+ e^{bx})}dx$ where $a,b > 0$. What is the difference between confidence intervals and hypothesis testing? I have read about   with some commentators suggesting that hypothesis testing should not be used. Some commentators suggest that confidence intervals should be used instead.    What is the difference between confidence intervals and hypothesis testing? Explanation with reference and examples would be appreciated. How to typeset subscript in usual text mode? I have one site with two languages: English and Spanish for example. What would be the proper convention to name image files?  From my point of view it would be stupid to duplicate image and then name it according to on which site it will be uploaded. It would be waste of resources IMO and unnecessary job to do.  What do you think about this one? Selected references without hyperlink When using the hyperref package, is it possible to tell LaTeX not to create a link for some references?  In my case the page number is displayed in the footer in  \fancyhf[FC]{\thepage\ of \pageref{pg:end}}   which is what I want. Unfortunately every single page in the document then has a link to the final page, which is a bit silly.  Any ideas on how to fix that? I'm trying to wrap my head around this for a while now. It's a simple question for what I think will be a not so simple answer. How would you go about modeling one leg of this stool? I would like to do it without using sculpt mode because I can't get things quite clean enough. How to find Windows 7 File Transfer History? Is it possible to find out which files are transferred to an external usb flash drive in certain period of time?   To be more clear. If I/someone have a flash drive and take some data from me. How do I know which files are copied? Finding out file copy hostory could be also a work around. Hey all I downloaded this file () but can't seem to be able to uninstall it. I tried looking online as well as the README file but there is only instruction for installing, not uninstalling the package.

For instance this would be a typical "hello world" application:   int _tmain(int argc, _TCHAR* argv[]) {     cout &lt;&lt; "Hello World";     return 0; }   What's the line I'm missing? A question on limsup I am including pages using Ajax but I also need to include their respective javascript files, which requires removing the previous javascript files from memory at the same time.  How can I unload the currently-loaded javascript files (as well as their code in memory) so that I can load the new page's files? They will more than likely conflict, so having multiple independent files' javascript files loaded.
