Plot the point whose polar coordinates are given. - Ploat the point whose polar coordinates are given. Then find two other pairs of polar coordinates of this point, one with r>0 and one with r<0
Points are (-1, pi/5)
Computing the Laplacian in different coordinate systems - Please assist with the attached problem.
(a) Calculate the Laplacian of function u(x,y,z) = x^3 - 3xy^2 + z^2 in 3D Cartesian coordinates.
(b) Convert the formula for u into formula for u involving ...
