diff - Maple Help

Degrees

 expand
 resolve degrees trig functions before calling main expand command
 int
 resolve degrees trig functions before calling main int command
 diff
 resolve degrees trig functions before calling main diff command
 solve
 resolve degrees trig functions before calling main solve command
 trigsubs
 resolve degrees trig functions before calling main trigsubs command

 Calling Sequence diff( expr, ... ) expand( expr, ... ) int( expr, ... ) solve( expr, ... ) trigsubs( expr, ... )

Parameters

 expr - expression

Description

 • The Degrees package provides some "wrapper" commands that process degrees-based trig functions into their radians-based form before calling the main library command of the same name.  The result is then processed back into degrees form.
 • These functions are part of the Degrees package, so they can be used in the short form, for example expand(..), only after executing the command with(Degrees). However, they can always be accessed through the long form of the command by using for example Degrees:-expand(..).

Examples

 > $\mathrm{with}\left(\mathrm{Degrees}\right):$
 > $∫\mathrm{sind}\left(x\right)\phantom{\rule[-0.0ex]{0.3em}{0.0ex}}ⅆx$
 ${-}{\mathrm{cosd}}{}\left({x}\right)$ (1)
 > $\mathrm{expand}\left(\mathrm{sind}\left(x+y\right)\right)$
 ${\mathrm{sind}}{}\left({x}\right){}{\mathrm{cosd}}{}\left({y}\right){+}{\mathrm{cosd}}{}\left({x}\right){}{\mathrm{sind}}{}\left({y}\right)$ (2)

Compatibility

 • The Degrees[expand], Degrees[int], Degrees[diff], Degrees[solve] and Degrees[trigsubs] commands were introduced in Maple 2021.
