Amplitude is the height from the mean, or rest, value of the function to its maximum or minimum. The period is the distance required for the function to complete one full cycle. For the sine function, the amplitude is given by and the period is defined as. The same is true for a cosine function.
Sine and Cosine: Definition. The sine and cosine functions can be defined in a number of ways: Definition I: From a triangle. Given any angle q (0 Â£ q Â£ 90Â°), we can find the sine or cosine of that angle by constructing a right triangle with one vertex of angle q. The sine is equal to the length of the side opposite to q, divided by the length of the triangle's hypotenuse. The cosine is equal to the length of the side adjacent to q, divided by the length of the triangle's hypotenuse. In this way, we can find the sine or cosine of any q in the range 0 Â£ q Â£ 90Â°. Definition II: From the unit circle. Draw a unit circle, in that a circle of radius 1, centered at the origin of a 2-dimensional coordinate system. Given an angle q, locate the point on the circle that is located at an angle q from the origin.
