WebThe process is somewhat confusing to find the exact value, but here it is: Let x = 18° (therefore 5x = 90°) sin (3x) = cos (90° - 3x) = cos (5x - 3x) = cos (2x) sin (3x) = cos (2x) (Remember that x = 18°, so that is why this is true.) 3sin (x) - 4sin^3 (x) = 1 - 2sin^2 (x) (I expanded these.) Let y = sin (x) 4y^3 - 2y^2 - 3y + 1 = 0 WebThe first solution is 45° more than a multiple of 180°, so (180n)° + 45° should do. The second solution is 30° more than a multiple of 180° and (because of the "plus / minus") …

WebMay 9, 2024 · f( − x) = f(x) for all x in the domain of f The graph of an even function is symmetric about the y- axis. The cosine function is an even function because cos( − θ) = cosθ. 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, cos( − π 4) = cos(π 4) ≈ 0.707 See Figure 9.1.3.
