Taylor expanding with the HP50G

[Gil]

Thanks a lot to both of you, the given solutions worked.

I did for instance:
'X/(476/100+83/100*X)' X 5
TAYLR

And got:
'-98476016075/2907915115807744*X^6+1186458025/6109065369344*X^5+-14294675/12834170944*X^4+172225/26962544*X^3+-2075/56644*X^2+25/119*X'

Which command(s) could I use to get, if possible in one single step, the execution of :
98476016075/2907915115807744,
1186458025/6109065369344,
asf?

To get something simplified as
'-(3.38648179721E-5*X^6.+-1.9421269102E-4*X^5.+1.11379808344E-3*X^4.+-6.38756491227E-3*X^3.+3.66322999788E-2*X^2.+-.210084033613*X)'.
