7. The natural log function (Primarily for CFA Levels 2 and 3) The natural log function is intimately related to ex. In Level 1, you will use this function to calculate a continuously compounded return given a specific holding period return. The natural log function (LN) is also used when working Black-Scholes and Merton Model problems.

The natural log function is intimately related to ex. The only time you may need to use the natural log function (LN) is when working Black-Scholes and Merton Model problems. Example: The value of the stock is $45 (S) today and the exercise price of a call option that trades on that stock is $50 (X). Calculate the natural log of (S/X).

Use some of the computations they made to illustrate the definition. Even though all calculators have a log button, the students should understand what the output value means and they should be able to estimate logarithm values without a calculator. For example, log 0.45 is between –1 and 0 because = 0.1 and = 1.
Activity overview:
Activity Overview. In this activity, students use a combination of algebra and graphing to discover the properties of logarithms. Given an equation such as b = a2 and a table of values for a, students define x = log a and y = log b and graph the resulting sets on the coordinate plane, graphically “taking the log of both sides.”

The natural logarithmic function can be defined as the inverse of the exponential function, although a light treatment only of inverse functions is required at this stage. It is enough to establish the results e log e x =x, x>0 and log e e x =x although some teachers may prefer to present a more complete treatment.

The logarithmic function with base 10 is called the common log. An example is . Common logs are usually written without the base. If a log is written without the base, it is a common log which has a base of 10. Common logs can be evaluated with the calculator using the button. Assignment #5: Use the calculator to evaluate
Evaluating Logarithms on the TI-84 Plus
Press ( ( to return to the Home screen. Use l to evaluate log(100). Because 102 = 100, the calculation returns a value of 2. Try finding the exponent for other values of 10x such as log(64) as shown. Record your findings. What happens if the base of your exponential function is not 10? How does that affect the log?
Functional Requirements Document Template
A function is described as a set of inputs, the behavior, and outputs. Functional requirements may be technical details, data manipulation, calculations and processing and other specific functionality that define what a system is supposed to accomplish. Functional requirements specify particular results of a system and drive the application ...
