% | Previous result |
True, False | Boolean constants |
EndOfFile | End-of-file marker |
Infinity | Constant representing mathematical infinity |
Pi | Mathematical constant, 3.14159... |
Undefined | Constant signifying an undefined result |
Typical examples are Simplify(%) and PrettyForm(%)to simplify and show the result in a nice form respectively.
In> Taylor(x,0,5)Sin(x) Out> x-x^3/6+x^5/120; In> PrettyForm(%) 3 5 x x x - -- + --- 6 120 |
Note that for most analytic functions Yacas understands Infinity. Thus Infinity*2 will return Infinity, and a < Infinity will evaluate to True.
In> 2*Infinity Out> Infinity; In> 2 |
In> Sin(3*Pi/2) Out> -1; In> Pi Out> Pi; In> N(Pi) Out> 3.1415926535; |
In> 2*Infinity Out> Infinity; In> 0*Infinity Out> Undefined; |
