Martin Kreuzer says one of his students produced a C4 package for computing approximate values of transcendental functions. He suggests that it could be cleaned up and released with CoCoA-5.

History

#1 Updated by John Abbott almost 9 years ago

  • Priority changed from Normal to Low

JAA thinks it could occasionally be handy to have such functions available from inside CoCoA-5.

Martin gave little information about what exactly the package contains.

#2 Updated by Anna Maria Bigatti about 7 years ago

I have a package myself called taylor.
Maybe I could show it to you and decide.

#3 Updated by Anna Maria Bigatti about 7 years ago

I've checked it in (not documented).

/**/ DecimalStr( TaylorArcSin(0.123456789) , 10);
0.1237725724
/**/ DecimalStr( TaylorSin(TaylorArcSin(0.123456789)) , 10);
0.1234567890
