search for: tangent

Dear all R-users, I would like to draw a tangent of a given function for a particular (given) point. However the straight line representing it should not cut any axis, it should be a small line. Can anyone tell me how to do this? Thanks, Arun [[alternative HTML version deleted]]

Full_Name: Peter Fortini Version: 2.0.1 OS: Windows 2000 Submission from: (NULL) (65.246.187.164) When the imaginary part of the argument is very large, the complex tangent function returns 0+NaNi. For example, tan(1+1000i)=0+NaNi; it should be 0+1i Easy to fix in complex.c, as the original NaN came from division of sinh and cosh that had reached machine infinity. static void z_tan(Rcomplex *r, Rcomplex *z) { double x2, y2, den; x2 = 2.0 * z->r; y2...

Dear all, We seem to have found a "strange" behaviour in the hyperbolic tangent function tanh on Windows. When running tanh(356 + 0i) the Windows result is NaN + 0.i while on Mac the result is 1 + 0i. It doesn't seem to be a floating point error because on Mac it is possible to run arbitrarily large numbers (say tanh( 9999996778736487675192381923481248123412341823748172398...

Hi, I plan to propose 'Math Aware search' project. After the literature review on the topic, I found Tangent or MIaS system would be a good start. With that, I studied both of the systems well. I plan to pick Tangent because it performs better. Also, it has a good literature(thesis report and few papers available) and reference code available. I keep the summary of both the system, I welcome any opinion...

Hello Les, Thanks for that info. I'm playing with this now and although the 'failover' process seems rather slow, it does seem to be doing what I need. I setup a subdomain entry to point to 4 IP's, only one if which is actually working, and indeed, when IE get's a non-active IP, it eventually goes to the next one until it finally finds the actual live IP. Once it gets the

...eople > continue to feed him. I assume the former is a reference to me. As far as the latter, you might re-think your singularity focus. As I've said before, you can't complain about me without complaining about others too. I.e., I try to point out things with_out_ going down into the tangent. Then people "get smart" with me believing what I say is not true. I can then either "let it go" and then people dismiss my offering of my experience and knowledge. Or I can correct them with the tangent. It's a catch-22 for all of us. > If people want to feed the troll...

I hate following up to myself, but I thought a clarification of one point (specifically WRT RC5 which was mentioned in the original question) might be worthwhile...because what I should have said originally was that "To the best of my non-legally- admissible knowledge, however, none of the algorithms in the current *OpenSSH* implementation are currently encumbered by patents that would

Hello ! I have a quick question about loops. For example, I have a 1 * 1 square and its inscribed circle tangent i, whose radius, of course, is also 1. The loop here is as the following: generate n points, say 5, in the square randomly repeatedly until we have five in total in the circle, then we stop, otherwise we continue. I do not know how ! Help me Please ~ Thank you very much for your time. You...

I have question about log2 transformation and performing mean on log2 data. I am doing analysis for ELISA data. the OD values and the concentration values for the standards were log2 transformed before performing the lm. the OD values for samples were log2 transformed and coefficients of lm were applied to get the log2 concentration values. I then backtransformed these log2 concentrations and the

Hi I have read various info, and mailing list archives, but have not found an answer to the following. I have a few servers with configurations similar to the following: They each have multiple uplinks to the Internet, and a sample config is as follows: eth1 is 192.168.0.1, connected to 192.168.0.2 eth2 is 192.168.1.1, connected to 192.168.1.2 My default route looks like: ip route add scope

Can anyone point me to a sample or information on using MeetMe like this? Conference room is set up with 2 PINs, one for the moderator and one for the participants. Participants get music until the moderator joins (to avoid wild, un-moderated tangents). Call is ended and all participants are kicked out when the moderator leaves (or the moderator can kick everyone out via phone keypad). Asking too much, or simple stuff?

...ten attempt to represent thousands or tens of thousands of points, but all I read from them are density and distribution --- the gene names cannot be shown. At what point, would a sunflowerplot-like display or a smooth gradient be better? When two data points drawn as 50% gray disks are small and tangent, are they perceptually equivalent to a single, 100% black disk? Or a 50% gray disk with twice the area? What problems are known about plotting with disks --- do viewers use the area or the diameter (or neither) to gauge weight? As you can tell, I'm a non-expert, mixing issues of data interp...

...t happen when I boot into Gentoo normally. How do I fix this? 2) X11. So after Xen does its initializing business, it boots up the Gentoo filesystem because I''ve put root=/dev/hda4 in my grub.conf. When it tries to start gdm, it fails completely. How do I get Xen to support X11? As a tangent to this, all of Xen''s binaries and such are installed on the Gentoo filesystem, as the installation documentation didn''t specify that the files should go anywhere else. Should Xen''s files and such have been installed to a completely new root filesystem, or is it ok that...
