1. 3. For the function , use Eq. (A.4) to write a general expression for the slope. This expression for the slope will depend on the initial value of , , and on the change in ,

. For values of sufficiently small that the term ( ) can be ignored, show that the slope depends only on the initial value of

, . What is the slope of the function (which is the same as the slope of the tangent line) when
