Finally, the secant function is the reciprocal of the cosine function, and the secant of a negative angle is interpreted as sec (− θ) = 1 cos (− θ) = 1 cos θ = sec θ. sec (− θ) = 1 cos (− θ) = 1 cos θ = sec θ. The secant function is therefore even. To sum up, only two of the trigonometric functions, cosine and secant, are even.Mar 3, 2021 · For expository writing, our writers investigate a given idea, evaluate its various evidence, set forth interesting arguments by expounding on the idea, and that too concisely and clearly.

So minus two times 50, times 60, times 60, times the cosine of theta. This works out well for us because they've given us everything. There's really only one unknown. hernando county arrests and mugshots Besides the two sides, you need to know one of the inner angles of the triangle. Let's say it's the angle γ = 30° between the sides 5 and 6. Then: Recall the law of cosines formula c² = a² + b² - 2ab × cos (γ) Plug in the values a = 5, b = 6, γ = 30°. We obtain c² = 25 + 36 - 2 × 5 × 6 × cos (30) ≈ 9.
