The minimum and the maximum of a trigonometric function are shown in the diagram. a) Write a cosine equation for the function b) Determine the value of the y – intercept, correct to three decimal places
In this section, we will begin an examination of the fundamental trigonometric identities, including how we can verify them and how we can use them to simplify trigonometric expressions. 1) We know g(x) = cosx is an even function, and f(x) = sinx and h(x) = tanx are odd functions. What about G(x) = cos2x, F(x) = sin2x and H(x) = tan2x?
Let A = (1 - cos θ) (1 + cos θ) (1 + cot2θ) = 1 and B = 1. Let A = cot θ + tan θ and B = sec θ csc θ. Let A = tan4 θ + tan2 θ and B = sec4 θ + sec2 θ. We always appreciate your feedback.
Precalculus: Fundamental Trigonometric Identities Practice Problems Questions 1. Evaluate without using a calculator; use identities rather than reference triangles. Find secθ and cscθ if tanθ = 3 and cosθ > 0. 2. Find all solutions to the equation 2sin2 x = 1 in the interval [0,2π). 3. Find all possible solutions to 3sint = 2cos2 t. Page ...
