sum and difference formula examples We can use the sum and difference formulas to identify the sum or difference of angles when the ratio of sine cosine or tangent is provided for each of the individual angles To do so we construct what is called a
In summary we have the following two formulas of cosine sum and cosine difference Cosine sum formula cos alpha beta cos alpha cdot cos beta sin alpha cdot sin beta Cosine difference formula cos alpha We can use the sum and difference formulas to identify the sum or difference of angles when the ratio of sine cosine or tangent is provided for each of the individual angles To do so we construct what is called a reference triangle to
