[Bug] Calculus calculation in xcas
(i) calculating indefinite integrals


(1)
Xcas can calculate this
Code:
int(x^-n,x)
But can't calculate this
Code:
int(1/x^n,x)

(2)
Multiple integral questions in this article


(ii) In terms of derivative
(1)
Code:
tcollect(laplacian(f(r*cos(theta)*cos(beta),r*cos(theta)*sin(beta),r*sin(theta))​,[r,beta,theta]))

(2)
Code:
zeros(diff(f(x,y,z(x,y)),[x,y]),diff(z(x,y),[x,y]))



thank you parisse!
