P := Matrix(51, 3): > R := 0.6e-1*(arctan(10*s/1.3+(-10)*.3)/Pi+1/2) ; y := evalf((-1)*0.6e-1*(arctan(10*s/1.3+(-10)*.3)/Pi+1/2)*cos(6*Pi*s/1.3)); > z := evalf(0.6e-1*(arctan(10*s/1.3+(-10)*.3)/Pi+1/2)*sin(6*Pi*s/1.3)); > for i from 1 to 51 do P[i, 1]:= evalf(Int(sqrt(1-((6*Pi/(1.3)*0.6e-1)*R(s))^2-(D(R))(s)^2), s = 0 .. 0.26e-1*i, 5, _Dexp)); end do; >for i from 1 to 51 do P[i, 2]:= y(0.26e-1*i); end do; >for i from to 51 do p[i, 3]:= z(0.26e-1*i) end do; I want paint the 3D-line by these points . what can I do? use plot3d(?) ?? Need help! Thank you! liu
