tabvar(sin(x)) question... - webmasterpdx - 11-23-2017 07:03 AM
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... - webmasterpdx - 11-23-2017 07:09 AM
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

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

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

-X-> indicates that it is a function, _x is imho a variable introduced by the CAS, when I copy your simplify(...) stuff into my command-line 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(...)

I'm using beta v2...are you?

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