sin sum and difference identities These are also known as the angle addition and subtraction theorems or formulae The angle difference identities for and can be derived from the angle sum versions by substituting for and using the facts that and They can also be derived by using a slightly modified version of the figure for the angle sum identities b
Opposite Sine Cosine and Tangent The three main functions in trigonometry are Sine Cosine and Tangent They are just the length of one side divided by another For a right triangle with 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
