HP49-50G : Taylor - Gil - 10-07-2021 04:12 PM
Suppose I have
Eq1
'(1+SIN(X)^2)/(1-SIN(X)^2)^.5'
in stack level 2
Then I execute
8 TAYLR
No answer, but an output message:
"Mode switch not allowed here".
How can I get the polynomial answer?
Thanks for your help.

Actually, the equation is
'(1.93185135484E-3*SIN(X)^2+1)/
(1-6.6943800229E-3*SIN(X)^2)^(1/2)'
X 8 TAYLR
to try and get a Taylor's polynome.
Thanks for your help.

It seems that we cannot work here with reals (with numbers presenting a dot format), but only with integers (and or with defined variables).
