Hello,

Hi, everyone, I got the expression,
sin(t)^8 + 4*sin(t)^6*cos(t)^2 + 6*sin(t)^4*cos(t)^4 +
4*sin(t)^2*cos(t)^6 + cos(t)^8
actually it is 1. how can I get it?
Here you go:
sage: t = var('t')
sage: a = sin(t)^8 + 4*sin(t)^6*cos(t)^2 + 6*sin(t)^4*cos(t)^4

Thanks in advance!
The secret is the method fullsimplify
var('t')
A = sin(t)**8 +
Thank you very much.

Thank you.
It confused me how can I know all about the method.
Is there some efficient way to know all of them?
The easiest way is to use tab-completion. For example, if ex is your
object, type in ex.simplify_ and then press TAB.
