@ -22328,10 +22328,10 @@ complicated trigonometric expressions. For example, while @kbd{a s}
can reduce @samp{sin(x) csc(x)} to @samp{1}, it will not simplify
@samp{sin(x)^2 csc(x)}. The command @kbd{I a s} can be used to
simplify this latter expression; it will transform @samp{sin(x)^2
csc(x)} into @samp{sin(x)}. However, @kbd{I a s} will also perform some
``simplifications'' which may not be desired; for example, it will
transform @samp{tan(x)^2} into @samp{sin(x)^2 / cos(x)^2}.
Similar to the @kbd{I} prefix, the Hyperbolic prefix @kbd{H} will
csc(x)} into @samp{sin(x)}. However, @kbd{I a s} will also perform
some ``simplifications'' which may not be desired; for example, it
will transform @samp{tan(x)^2} into @samp{sin(x)^2 / cos(x)^2}. The
Hyperbolic prefix @kbd{H} can be used similarly; the @kbd{H a s} will
replace any hyperbolic functions in the formula with the appropriate
combinations of @samp{sinh}s and @samp{cosh}s before simplifying.
