Use the dot product formula: u . v = | u | | v | c o s ( ? ) to find the angle between the vectors i - 2 j + k and 2 i -j + k. Use the dot product formula: u.v= |u||v|\cos \theta, to find the angle between the vectors i - 2j + k and i -...
How to find the normal of two vectors?Cross product in Vectors:This problem involves finding the vector which is perpendicular to any two given vectors. The idea is to use the concept of vector cross product which results in a vector that is perpendicular to each of the individual vectors....

ky | cos(theta_glass) kz | sin(theta_glass) where i have assumed that the wave propagates in the z-direction with the electric field polarized in the x-direction and that the two first layers are "air" and "glass". I am aware that COMSOL can do the assignment of k-vectors automat...
How to plot the five ellipses in the same figure?Here is my code, where when xi_a takes a new value from xi for each iteration, the semi-axes of my ellipse changes.as you go through your calculations in a loop, then create a second loop to do the plots.Just...
rotation_matrix = [cos(theta) -sin(theta) 0; sin(theta) cos(theta) 0; 0 0 1]; % Apply the rotation to axes rotated_x_axis = x_axis * rotation_matrix; rotated_y_axis = y_axis * rotation_matrix; rotated_z_axis = z_axis * rotation_matrix; ...
Your x and y values that come out will be vectors that are scattered around, not a regular grid. You can only use mesh() when the x and y represent grids. If you want a gridded surface then you should look at triscatteredinterp() or the newer griddedinterpolant()In...
