The systems of equations that govern certain phenomena (in electrical circuits, chemical kinetics, etc.) contain a combination of differential equations and algebraic ...

GeoDirection[{lat_1, long_1}, {lat_2, long_2}] gives the azimuthal direction from one latitude-longitude position on the Earth to another.GeoDirection[pos_1, pos_2] gives the ...

GeoDistance[{lat_1, long_1}, {lat_2, long_2}] gives the geodesic distance in meters between latitude-longitude positions on the Earth.GeoDistance[pos_1, pos_2] gives the ...

TraceOn is an option for Trace and related functions which specifies when tracing should be switched on.

On most computer systems, Mathematica can produce not only graphics but also sound. Mathematica treats graphics and sound in a closely analogous way. For example, just as you ...

DSolve returns a general solution for a problem if no initial or boundary conditions are specified. The general solution to this equation is returned. However, if initial or ...

Rescale[x, {min, max}] gives x rescaled to run from 0 to 1 over the range min to max. Rescale[x, {min, max}, {x_min, x_max}] gives x rescaled to run from x_min to x_max over ...

ArcSinh[z] gives the inverse hyperbolic sine sinh -1 (z) of the complex number z.

Particularly in the physical sciences, it is common to use measurement errors as weights to incorporate measured variation into the fitting. Weights have a relative effect on ...

Radon[image] gives an image representing the discrete Radon transform of image.Radon[image, {w, h}] specifies the width w and the height h of the resulting image.Radon[image, ...
