sum and difference identities The sum and difference identities are used to find the value of trigonometric functions at angles that can be written as the sum or difference of the special angles 0 30 45 60 90 and 180
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 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 Pythagorean Theorem along with the sum and difference formulas can be used to find multiple sums and differences of angles The cofunction identities apply to complementary angles and pairs of reciprocal functions Sum and difference formulas are useful in verifying identities Given an identity verify using sum and difference formulas Begin with the expression on the side of the equal sign that appears most complex Rewrite that expression until it matches the other side of the equal sign
