Question: Function evaluation goes wrong, why?

Hey and Thanks for your input.


 

restart; f := ((1/2-I*t)^(-s)-(1/2+I*t)^(-s))/(2*I); fc := evalc(f); `assuming`([simplify(int(f, t = 0 .. infinity))], [s > 1]); `assuming`([simplify(int(fc, t = 0 .. infinity))], [s > 1])

-((1/2)*I)*((1/2-I*t)^(-s)-(1/2+I*t)^(-s))

 

exp(-(1/2)*s*ln(1/4+t^2))*sin(s*arctan(2*t))

 

2^(s-1)/(s-1)

 

(1/2)*4^s/(s-1)

(1)
