How to find the period of a sine/cosine graph?

The period of a sine graph is equal to the length of one full cycle. To find the period, use the Pythagorean Theorem to determine the length of the hypotenuse of a right triangle with the two legs being the amplitude of the graph’s peaks and valleys. This will give you the length of one cycle. You can use this method to find the period of all sine graphs, although it might be easier to use a calculator.

How to find the period of a sine wave graph?

To find the period of a sine wave plotted in Excel, you will need to use the Period box in the Sine Wave Wizard. Once you have created a sine wave graph in Excel, click the Period box under the Sine Wave Wizard tool. To get the period of the sine wave, enter the period of the wave in seconds in the box.

How to find the period of a sine wave?

To find the period of a sine wave, you need to know the amplitude of the wave. This is the distance from the baseline to the peak. Once you have the amplitude, you can find the period by dividing the length of the wave by the amplitude. The period of a cosine wave is the same as the period of a sine wave that has the same amplitude and peaks at the same points as the cosine wave.

How to find the period of a sine wave equation?

You can find the period of a sine wave using the formula P = 2π√T, where T is the period and P is the period in seconds. This equation is shown in the figure below.

How to find the period of a cosine graph?

To find the period of a cosine graph, we use the Pythagorean Theorem. Let’s say your graph has a period of 2π. To find the period in degrees, you need to convert the radian measurement to degrees. To do this, multiply the period in radians by two to get the period in degrees. So the period in degrees of a graph that has a period of 2π is simply two times pi.
