WebNov 8, 2024 · We want period of c o s 2 ( x) we know that cos 2 ( X) = 1 2 ( 1 + cos 2 x) now consider only cos 2 x as the remaining are constants then it is in the form cos ( a x + b) that is cos ( 2 x + 0) we know that period of cos x = 2 π a now substitute 2 in place of a that is 2 π 2 = π. Then the period of cos 2 ( x) = π Share Cite Follow WebJun 2, 2024 · sin2θ = 1 2(1 −cos(2θ)) so has period π. Explanation: We know the answer is π. Let's see why. The period of sin(x) is 2π and the period of sin(kx) is thus 2π k. That doesn't tell us the period of sin2x until we apply one of the double angle formulas for cosine: cos(2x) = 1 − 2sin2x sin2x = 1 2(1 − cos(2x))

WebMay 4, 2024 · If you multiply by a constant on the outside and on the inside, as in y = − 3sin2x, you will affect both the amplitude and the period. Here is the graph of y = − 3sin2x: Example. Problem: Determine the amplitude and period of y = − 3cos2x. Answer. Use the formula for amplitude, with a = − 3. Weby = -sin(1/2 * x) determine the period and amplitude dave the diver keybindings

WebMay 28, 2024 · The graph of cosecant, which is shown in Figure 2.2. 2, is similar to the graph of secant. Figure 2.2. 2: The graph of the cosecant function, f ( x) = csc x = 1 sin x. FEATURES OF THE GRAPH OF Y = A csc ( B x) The stretching factor is A . The period is 2 π B . The domain is x ≠ π B k, where k is an integer. WebNov 30, 2024 · The period of the basic sine function. y = \sin (x) y = sin(x) is 2π, but if x is multiplied by a constant, that can change the value of the period. If x is multiplied by a number greater than 1, that "speeds up" the function, and the period will be smaller. It won't take as long for the function to start repeating itself. WebNormally the period of sin (x) would be 2pi long. Lets compare sin (4x) and sin (x): At x=1 sin (x) = sin (1) , sin (4x) = sin (4) At x=2 sin (x) = sin (2) , sin (4x) = sin (8) As you can see in sin (x) x goes up by plus 1 every time (0, 1, 2, 3, 4,...). On the other hand sin (4x) x goes up by plus 4 every time ( 0, 4, 8, 12, 16,...). garzey\\u0027s wing watch online
