GRADIENT o z = x².y² z = e(x² + y²) z = x.e-(x²+x²) DIVERGENCE 。 A=x.z.a.-y²a + 2x²y.az A=x²³a+ya+za A=x²y.a-y²za+z²x.a O O CURL Z O 。 A=y²a₂ + (2xy + z²).a₁2yz.a o A=x.y.a,+yz.a,+zx.a₂ o A=x.y².a-yz².a+zx².a. 2. Using the definitions of vector operators in Cartesian system above, prove the following 2 null-identities (analytically) for any vector field "A": Vx(VA)=0 curl of the gradient of any scalar field is zero. V-(VxA)=0 divergence of the curl of any vector field is zero. 3. Prove the 2 null identities using MATLAB. You can select the field functions used in the examples. 4. The characteristic impedance of a medium is defined as the ratio of Electric field and Magnetic Field propagating in that media as shown in the equation below. E, (z) n = Now suppose that you have the data of measured values of Electric Field Ho(z) and Magnetic field in 15 different measurement setups. The resulting values are in the following table: Number of measurements 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Find the average value of impedance. 5.
