Using Algebra to Simplify Trigonometric Expressions We have seen that algebra is very important in verifying trigonometric identities, but it is just as critical in simplifying trigonometric expressions before solving.
WebCofunction Identities. In trigonometry, a function f is said to be a cofunction of a function g if. whenever α and β are complementary angles, that is, two angles whose sum is 90° or π/2 radians: Using the sine and cosine subtraction formulas, we have already derived the cofunction identities. Now we will prove other similar formulas. Webidentity 2 says that “the sine of an angle equals the cosine of the complement of the angle.” The sine and cosine functions are related by complementary angles in this particular way. We call the sine and cosine functions “cofunctions” because of this relationship. Identities 3 …

WebThe cofunction identities are summarized in Table 7.2.2. Notice that the formulas in the table may also justified algebraically using the sum and difference formulas. For example, using cos(α − β) = cosαcosβ + sinαsinβ We can write cos(π 2 − θ) = cosπ 2cosθ + sinπ 2sinθ = (0)cosθ + (1)sinθ = sinθ
