sum and difference of trigonometric functions 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 help find each component of the sum and difference formulas
The sum and difference formulas in trigonometry are used to find the value of the trigonometric functions at specific angles where it is easier to express the angle as the 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 help find each component of the sum and difference formulas
