Jacobian How to use the chain rule? When you have a composition of functions (dw/ds, dw/dt)= (df/du, df/dv)(du/ds, dv/ds, du/dt, dv/dt) so it gives a vector Classify critical points 1. differentiate WRT each variable x and y. 2. set them equal to 0. then solve for the values (often take the equation that is easy to factorize and take its values. 3. replace the values obtained in the other partial equation set equal to 0 to get the points ***trick: you can add the equations some...

(T/F) if u and v are not ‖, |scal_v_u|<|u| - True. Geometrically: scal_v_u is the magnitude of the ‖ component of u in the direction of v; the only way that this magnitude can be equal to the magnitude of the vector u itself is if u is in the same direction as v. (T/F) if u and v are not ‖, |scal_v_u|<|scal_u_v| - Not enough information given. Geometrically: scal_v_u is the magnitude of the ‖ component of u in the direction of v. Vice versa for scal_u_v. If the magnitude of u ...
