FEYN CALC SYMBOL

PowerSimplify


simplifies (-x)^a to (-1)^a x^a and (y-x)^n to (-1)^n (x-y)^n; thus assuming that the exponent is an integer (even if it is symbolic). Furthermore (-1)^(a+n) and ⅈ^(a+n) are expanded and ⅈ^(2 m) (-1)^m and (-1)^(n m) 1 and (-1)^(n m) (-1)^m for n even and odd respectively and (-1)^(-n) (-1)^n and ⅇ^(ⅈmpi) (-1)^m.
