How to solve cofunctions
WebStep 1: In deriving the first cofunction identity, we use the difference formula or the subtraction formula for cosine; Step 2: Evaluate the trigonometric functions that are … WebSo sine and cosine are cofunctions, secant and cosecant are cofunctions, and tangent and cotangent are cofunctions. That is how the functions cosine, cosecant, and cotangent got the “co” in their names. The Cofunction Theorem says that any trigonometric function of an acute angle is equal to its co-function of the complementary angle.

WebUsing the right angle with SOH CAH TOA creates a problem that you discovered -> the opposite side IS the hypotenuse and there is no way to distinguish between the two legs. Use a different angle. If one isn't given, use inverse sine, cosine, or tangent with the two given sides to find it. ( 5 votes) darkally 9 years ago WebThe cosine function is an even function because cos( − θ) = cos θ. For example, consider corresponding inputs π 4 and − π 4. The output of cos(π 4) is the same as the output of cos(− π 4). Thus, See Figure 3. Figure 3 Graph of y = cosθ For all θ in the domain of the sine and cosine functions, respectively, we can state the following:
