What Is a Sine Graph?
A sine graph is a graph displaying the function of y = sin x. A sine graph has a function which may also be described as a sinusoidal wave. It repeats itself as it moves along the x-axis, and the cycle taken for a repetition is known as the period of the sine graph. A number of different analyses can be done on the period and amplitude of a sine graph, and there are many interesting results that can be gleaned from this crucial function. Sine itself is a measurement given to an angle, representing the ratio between the opposite of the far side to the length of the hypotenuse. It can be contrasted with the cosine, which represents the ratio between the adjacent side and the hypotenuse, and the tangent, which represents the ratio between the opposite side and the adjacent side. Each function also has a reciprocal, for example the cosecant, the reciprocal of sine, which represents the ratio between the hypotenuse and the opposite side. The best way to understand a sine graph is to look at
