Hi everyone Here I try to define a real value vector and find out its norm:
sage: R.<r,p>=RR[] sage: rvec=vector([r*cos(p),r*sin(p)]) sage: rr=rvec.norm() sage: rr.simplify_full() sqrt((abs(cos(p))^2 + abs(sin(p))^2)*abs(r)^2) which must be: r How can I define a vector that its norm hasn't abs() function? -- You received this message because you are subscribed to the Google Groups "sage-support" group.
