tabvar(sin(x)) question...
I've been playing with some of the new commands...
tabvar(sin(x)) gives a table of operations. However, I don't understand some of the symbols. What do the diagonal up and diagonal down arrows mean?

RE: tabvar(sin(x)) question...
I think the arrows mean "increasing" and "decreasing".
I also did a simplify(cot(pi*x)^(1/16)  10) and I got this as result: _x>(table(_x+1 = (cos(pi*x)/sin(pi*x))^(1/16) 10)) Please explain what this means? Thx Donald

cot(x)=cos(x)/sin(x)

...and...? :)
....I meant what does table() mean? What is _x? etc..

RE: tabvar(sin(x)) question...
X> indicates that it is a function, _x is imho a variable introduced by the CAS, when I copy your simplify(...) stuff into my commandline I get a syntax error, entering it by hand results in a long line containing cos, cosh, sin, sinh as a result of the attempt to rewrite that, no table(...)

As usual the newest version 13012, no such issue here.
