ln x for x > 0 . for which they are continuous. cos ( x ) and sin ( x ) for all x. Suppose that f ( x ) is continuous on [a, b] and let M be any number between f ( a ) and f ( b ) . Then there exists a number c such that a < c < b and f ( c ) = M . If y = f ( x ) then all of the following are equivalent notations for the derivative.
In this guide, we explain the four most important natural logarithm rules, discuss other natural log properties you should know, go over several examples of varying difficulty, and explain how natural logs differ from other logarithms. What Is ln? The natural log, or ln, is the inverse of e.

In this booklet we will demonstrate how logarithmic functions can be used to linearise certain functions, discuss the calculus of the exponential and logarithmic functions and give some useful applications of them.
In this booklet we will use both these notations. We can use these results and the rules that we have learnt already to differentiate functions which involve exponentials or logarithms. e (x2 + 3x + 1). We solve this by using the chain rule and our knowledge of the derivative of log x. d = e3x2 (3x2) × dx = 6xe3x2.
When computing limits it may be useful to try the following techniques: If the function is continuous at the point, just plug in the point. If it is not continuous at the point try the following: 2 Simplify by factoring or rationalizing. 2 Write in the form “0 0” or “1 1” and apply L’Hospital’s Rule.
Take the natural logarithm of both sides. ln y = ln x + 1 2 ln (2 x + 1) − x ln e − 3 ln sin x Step 2. Expand using properties of logarithms. 1 y d y d x = 1 x + 1 2 x + 1 − 1 − 3 cos x sin x Step 3. Differentiate both sides. d y d x = y (1 x + 1 2 x + 1 − 1 − 3 cot x) Step 4. Multiply by y on both sides. d y d x = x 2 x + 1 e x sin ...
