Here are a few things you may want to include: 1. Differentials and Linear Approximation: y is the actual amount that the function changes if you move over x from the point x , and you can find it using y y ( x x) y ( x) . dy is the approximation for how much the function changes by looking at the tangent line to the function at x . You can find dy by dy f '( x ) dx f '( x) x . It is important to remember that dx x but dy y . You can use differentials to help approximate the value of a function near a value, a , where f ( a ) is easy to evaluate, by using the formula for the tangent line at a , which is f ( x ) f ( a ) f '( a )(...
