How to Find the Amplitude and Period of the Cosine Equation

The video tutorial explains how to find the period of a function using the formula 2π/B. It clarifies that B is the coefficient of X in the equation and demonstrates how to handle fractions in the denominator by multiplying by the reciprocal. The example provided shows that multiplying 2π by the reciprocal of 2/3 results in a period of 6π.
