Organizing and summarizing search results for youTo find the amplitude of a cosine function:- Compare the function to its general form: The general form of a cosine function is (y = A \cos(Bx)). The coefficient (A) is the amplitude of the cosine. If there is no number in front of the cosine function, the amplitude is 1.
- Remember that the basic cosine function has a maximum value of 1 and a minimum of -1: For any value of (\theta), the amplitude of the cosine function (A \cos(\theta)) is (|A|).
- For the cosine function (y = a \cos(x)), the amplitude represents half the distance between the maximum and minimum values of the function, and it is given by (|a|).
- The period of the cosine function (y = a \cos(bx)) is given by (2\pi/|b|).
