Electrodynamics. Consider a linear medium where and are both zero in the region of interest. Show that the Maxwell's equations are invariant to the transformation where is a dimensionless constant and is a constant but arbitrary angle. In other words, if and are solutions of Maxwell's equations, show that and too. Consider the special case and thus show that, in...

Changes in one or more of the determinants of demand (consumer tastes, the number of buyers in the market, the money incomes of consumers, the prices of related goods, and expected prices) shift the market demand curve. A shift to the right is an increase in demand; a shift to the left is a decrease in demand. A change in...
