(a) For the one-dimensional wave equation, for what values of x0 (x, t, t0 fixed) is G(x, t; x0, t0) = 0? (b) Determine the answer to part (a) using the reciprocity property.

Section 3.7 Cross Products In this section, we’ll be looking for a vector that is orthogonal to two given vectors. There are an infinite number of answers! One specific one is called the cross product. THE CROSS PRODUCT OF TWO THREE-DIMENSIONAL VECTORS 1 u2...
