When radians are set as the angle unit, arccos() maps an element from to a value in. Real arguments outside and complex numbers are not allowed in degrees mode. In degrees mode, arccos() takes a real argument from, and the return value is in the range. The behavior of the function depends on both the angle unit setting (degrees or radians) and on whether complex numbers are enabled. Returns the inverse cosine of x, such that cos(arccos(x)) = x. The argument of csc() must be dimensionless. When radians are set as the angle unit, csc() will be 2π-periodic. Complex arguments are not allowed in degrees mode, regardless of the corresponding setting. In degrees mode, the argument is assumed to be expressed in degrees, such that csc() is periodic with a period of 360 degrees: csc(x) = csc(x+360). The behavior depends on both the angle unit setting (degrees or radians) and on whether complex numbers are enabled. Returns the cosecant of x, defined as the reciprocal sine of x: csc(x) = 1/sin(x). The argument of sec() must be dimensionless. |x|>10 77, SpeedCrunch no longer recognizes the periodicity of the function and issues an error. The argument may be complex.įor real arguments beyond approx. When radians are set as the angle unit, sec() will be 2π-periodic. In degrees mode, the argument is assumed to be expressed in degrees, such that sec() is periodic with a period of 360 degrees: sec(x) = sec(x+360). If you are interested in supporting this great project, SpeedCrunch offers many ways to donate you can find them here.Returns the secant of x, defined as the reciprocal cosine of x: sec(x) = 1/cos(x). The project is a free open-source software which is released under GNU General Public License.Ĭontribution is open for developers and users to report bugs or request new features, and translate the program into new languages. They can also download 32-bit (RPM, Deb and Generic package) as well as 64-bit.įor Windows systems, SpeedCrunch offers an installer package and a portable package that works without install in one single file. Linux's users can find SpeedCrunch in their software repository for Ubuntu, Debian, Fedora, Arch Linux, Manjaro and openSUSE. SpeedCrunch offers Windows, Linux and macOS generic software packages which ease install process. SpeedCrunch supports many languages as it's packed by a strong community of users and developers, it supports English Chinese (China, Taiwan), German, Italian, French, Polish, Portuguese, Romanian, Russian, Chzech, Spanish, Dutch, and more. Session manager with import/ export functions.Built-in formulas book and 150+ scientific formulas.Multi-platform: Windows, Linux and macOS.Variables functionality in SpeedCrunch allows users to store their results which comes handy for many specific users. It's fairly easy-to-use and works seamlessly on Windows, macOS and Linux.ĭespite its small size, SpeedCrunch is features-rich program with dozens of usable functions and options. SpeedCrunch is a lightweight calculator program without the traditional calculator buttons, It provides a simple powerful interface which make a use of the keyboard, mathematical terms and shortcuts and display results in interactive way as the user's type.īut many users my prefer old-school keyboard, so they can have an optional on-screen keypad from view menu. I have been never a fan of classical calculators user-interface, therefor I am always looking for and using command-line calculators.
