sind, cosd, ...
Trigonometric functions in degrees
arcsind, arccosd, ...
Inverse trigonometric functions returning degrees
sind(x) cosd(x) tand(x)
secd(x) cscd(x) cotd(x)
arcsind(x) arccosd(x) arctand(x)
arcsecd(x) arccscd(x) arccotd(x)
Arguments for these versions of trigonometric functions
must be given in degrees (1 radian = 180/Pi degrees)
Return values for these arctrigonometric functions
are in degrees.
When x is not a numeric value the returned expression will remain in the context of degrees. Some simplifications are automatically applied to reduce output returned from direct calls to these functions, whereas the Degrees:-Simplify command must be used to evaluate and reduce expressions containing these functions.
These functions are part of the Degrees package, so they can be used in the short form sind(..) only after executing the command with(Degrees). However, they can always be accessed through the long form of the command by using Degrees:-sind(..).
Evaluate trigonometric expressions using degrees
The Simplify command is needed to reduce symbolic expressions
expr ≔ sind⁡x2+cosd⁡x2
The sind, cosd, ... and arcsind, arccosd, ... commands were introduced in Maple 2021.
