The external secant function (abbreviated exsecant , symbolized exsec ) is a trigonometric function defined in terms of the secant function:
exsec θ = sec θ − 1 = 1 cos θ − 1. {\displaystyle \operatorname {exsec} \theta =\sec \theta -1={\frac {1}{\cos \theta }}-1.}
It was introduced in 1855 by American civil en... | https://en.wikipedia.org/wiki/Secans_exterior |

A secant plane is a plane containing a nontrivial section of a sphere or an ellipsoid , or such a plane that a sphere is projected onto. Secant planes are similar to tangent planes, which contact the sphere's surface at a point, while secant planes contact the surface along curves.

seccomp (short for secure computing [ 1 ] ) is a computer security facility in the Linux kernel . seccomp allows a process to make a one-way transition into a "secure" state where it cannot make any system calls except exit() , sigreturn() , read() and write() to already-open file descriptors . Should it attempt any ot... | https://en.wikipedia.org/wiki/Seccomp |
Second-harmonic imaging microscopy ( SHIM ) is based on a nonlinear optical effect known as second-harmonic generation (SHG). SHIM has been established as a viable microscope imaging contrast mechanism for visualization of cell and tissue structure and function. [ 1 ] A second-harmonic microscope obtains contrasts fro... | https://en.wikipedia.org/wiki/Second-harmonic_imaging_microscopy |
