# What types of simplify work now

I'm trying the various forms of simplify I see in the docs, but most say "not found" What exactly is going on? Have some been superseded? What ones still work in Sagemath 9.3 for Windows? i.e. "simplify_full()", "simplify_trig()", "simplify_rational()",\n "simplify_rectform()" "simplify_factorial()", "simplify_log()",\n "simplify_real()", "simplify_hypergeometric()",\n "canonicalize_radical()"

for instance:
simplify_trig?
Object `simplify_trig`

not found.
simplify_full?
Object `simplify_full`

not found.

Where am I confused?

I seem to recall using these but didn't use sage for a while. What works now?
