(30 points) The following three equations y -+-2w3 z z 4zu are satisfied at point Q : Fl (a) (b) (c) (d) Check whether point Q satisfies the system of three equations above. Calculate the Jacobian and check if the Jacobian IS non-zero at Q _ Write down the system for B:c/8z, By/Bz, Bw/8z_ Evaluate the system at point Q and use the Cramer's rule to solve it giving a numerical solution for 3/Bz, By/ Bz, 3w/8z_
