Finding the Period and Amplitude of a Graph

The video tutorial explains how to find the period and amplitude of a function. It begins by defining amplitude as the absolute value of the coefficient 'a' in the function's general form. The teacher demonstrates this with an example, showing that the amplitude is 3. The concept of absolute value is emphasized, especially when dealing with negative numbers. The tutorial then shifts to the period, defined as 2π divided by the coefficient 'B'. An example is provided where B is 2, resulting in a period of π. The importance of understanding these concepts for graphing is highlighted.
