WebFeb 1, 2024 · We will follow the steps below: Draw a right triangle with the angle given; Use cofunction identities to transform the function we're seeking into its cofunction; and Calculate the value of the cofunction by taking the ratios of the triangle's sides. WebSine Addition Formula Starting with the cofunction identities, the sine addition formula is derived by applying the cosine difference formula. There are two main differences from the cosine formula: (1) the sine addition formula adds both terms, where the cosine addition formula subtracts and the subtraction formula adds; and (2) the sine formulas have sin …
WebThen to solve for f (g (x)), you would plug in g (x) (the whole formula), in to f (x) for x. So... f (g (x)) = 2 (4/x) + 1 = 8/x + 1 This is just a simple example but you can do it with many … 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
