This is a simple trigonometric function calculator implemented in MATLAB. It can calculate sine (sin), cosine (cos), arcsine (arcsin), and arctangent (arctan) functions. Users can input either radians ...

The Atan2 function returns the arctangent, or inverse tangent, of the specified x and y coordinates as arguments. The arctangent is the angle from the x -axis to a line that contains the origin (0, 0) ...

The arctan function has a range between -π/2 and π/2 or -90° and 90° when measured in degrees. Methods to Calculate Arctan 1. Trigonometric Table or Calculator: One of the most straightforward ways to ...

This paper introduces the Arctan exponential distribution, a novel two-parameter trigonometric distribution. Various statistical properties of the distribution are examined, including hazard rate ...

Spread the loveIntroduction: Arctan, or arctangent, is one of the inverse trigonometric functions that relates the angle of a right-angled triangle to its opposite and adjacent sides. In general, ...
