Your phase shift is C / B. Find an equation for a cosine function that has amplitude of 3 5, a period of 270 , and a y-intercept of 5. For a simple sine or cosine function, you can set the value at 1 and the centerline at 0. Examples include x2, x4, x6, and cosine. We can add secant to the list of functions that we know are even functions. This interval from x = 0 to x = 2π of the graph of f(x) = cos(x) is called the period of the function.The period of a periodic function is the interval of x-values on … The B is used to calculate the period. Or we can measure the height from highest to lowest points and divide that by 2. 17. We can always calculate the period using the formula derived from the basic sine and cosine equations. Note. If we look at the cosine function from x = 0 to x = 2π, we have an interval of the graph that’s repeated over and over again in both directions, so we can see why the cosine function is a periodic function. For a simple sine or cosine function, you can set the value at 1 and the centerline at 0. That is, sec( ) = sec( ). Since the function is periodic with a period of 2π or 360°, we can find the cosine of any angle no matter how large it is. As you drag the point A around notice that after a full rotation about B, the graph shape repeats. Basically, the amplitude is A in the phase shift equation.

The Amplitude is the height from the center line to the peak (or to the trough). These are sometimes abbreviated sin(θ) andcos(θ), respectively, where θ is the angle, but the parentheses around the angle are often omitted, e.g., sin θ andcos θ. Period of other variations of the cosine function. These are sometimes abbreviated sin(θ) andcos(θ), respectively, where θ is the angle, but the parentheses around the angle are often omitted, e.g., sin θ andcos θ. The cosine function is also symmetrical about the y-axis. If the period is more than 2π then B is a fraction; use the formula period = 2π/B to find the exact value. List of trigonometric identities 2 Trigonometric functions The primary trigonometric functions are the sine and cosine of an angle.
