Question: Simplification of constant trig expression

t := (5/9)*Pi;
e:=tan(t) + 4*sin(t);

is -sqrt(3)  but how to make Maple show this?

This is what I tried

t := (5/9)*Pi;
e:=tan(t) + 4*sin(t);
convert(e,radical);
simplify(e,trig);
simplify(e,constant);
allvalues(e);

 

The command "is" and "identify" knows this

is(e=-sqrt(3));
identify(evalf[32](e))

In Mathematica, FullSimplify can do it.

 

Any suggestions in Maple to simplify like the above?

Maple desperately needs a new full_simplify() command.

Having to keep trying different commands by trial and error in the hope one works is not the right way to do things.
