Integration of RealSign and RealAbs #25

Closed amcostant closed 4 years ago

amcostant commented 5 years ago

Int[RealSign[a*t + b], t] results in Subst[Int[RealSign[t], t], t, b + a t]/a when MMA does RealAbs[b + a t]/a

and

Int[RealAbs[b + a t], t] results in Subst[Int[RealAbs[t], t], t, b + a t]/a when MMA does ((b + a t) RealAbs[b + a t])/(2 a)

I understand that the number of functions where the definite integral exists is quite limited. Thank you very much for the Rubi library

Sorry, integrating expressions involving RealSign and RealAbs is outside the domain of expressions Rubi is designed to handle.
