WebProduct Formulas. These relationships express the product of two sinusoids in terms of the sum of two sinusoids. Sometimes it is desirable to express the sum of two sinusoids in terms of a product of sinusoids, as in the description of modulated sine waves. These relationships are called the superposition relationships.
