Xcas can calculate this

But can't calculate this

Xcas can calculate this

Code:

`int(x^-n,x)`

Code:

`int(1/x^n,x)`

(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!
