calc: Yacas Language Mode

 
 7.8.5 Yacas Language Mode
 -------------------------
 
 The ‘d Y’ (‘calc-yacas-language’) command selects the conventions of
 Yacas, a free computer algebra system.  While the operators and
 functions in Yacas are similar to those of Calc, the names of built-in
 functions in Yacas are capitalized.  The Calc formula ‘sin(2 x)’, for
 example, is entered and displayed ‘Sin(2 x)’ in Yacas mode, and
 ‘‘arcsin(x^2)’ is ‘ArcSin(x^2)’ in Yacas mode.  Complex numbers are
 written are written ‘3 + 4 I’.  The standard special constants are
 written ‘Pi’, ‘E’, ‘I’, ‘GoldenRatio’ and ‘Gamma’.  ‘Infinity’
 represents both ‘inf’ and ‘uinf’, and ‘Undefined’ represents ‘nan’.
 
    Certain operators on functions, such as ‘D’ for differentiation and
 ‘Integrate’ for integration, take a prefix form in Yacas.  For example,
 the derivative of ‘e^x sin(x)’ can be computed with
 ‘D(x) Exp(x)*Sin(x)’.
 
    Other notable differences between Yacas and standard Calc expressions
 are that vectors and matrices use curly braces in Yacas, and subscripts
 use square brackets.  If, for example, ‘A’ represents the list
 ‘{a,2,c,4}’, then ‘A[3]’ would equal ‘c’.
