In many problems in the calculus of variations, you need to know the length ds of a short segment of a curve on a surface, as in the expression (6.1). Make a table giving the appropriate expressions for ds in the following eight situations: (a) A curve given by y = y(x) in a plane, (b) same but x = x

Consider the circuit shown in Figure 2146, in which three lights, each with a resistance R, are connected in parallel. The circuit also contains an open switch. (a) When the switch is closed, does the intensity of light 3 increase, decrease, or stay the same? Explain. (b) Do the intensities of lights

Dmw Lewis structures for each hypothetical molecule shown below, using the correct number of valence electrons for each atom. Determine which molecule makes sense because each atom has a complete valence shell and each bond has the correct number of electrons. Explain what makes the other molecules n
