ABSTRACT
For the following equations, the symbols f(x), g(x), etc., represent functions of x. The value of a function f(x) at x = a is denoted f(a). For the function y = f(x) the derivative of y with respect to x is denoted by one of the following: d y d x , f ′ ( x ) , D x y , y ′ . https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203743102/9cca8f32-4688-4a1e-80c2-a6c9068f5153/content/eq222.tif"/>
