The frequency and period are reciprocals of each other. Example: Determine the equation of a cosine function that has a frequency of 4. The frequency and period are reciprocals of each other so the period = . Since , we can replace the period with and solve for k. If , then . The cosine function with a frequency of 4 is f(θ)=cos(8πθ) . Find ...
