Amplitude. The "a" in the expression y = a sin x represents the amplitude of the graph.It is an indication of how much energy the wave contains.. The amplitude is the distance from the "resting" position (otherwise known as the mean value or average value) of the curve.In the interactive above, the amplitude can be varied from `10` to `100` units.

Sine, Cosine and tangent are the three important trigonometry ratios, based on which functions are defined. Below are the graphs of the three trigonometry functions sin x, cos x, and tan x.
Amplitude. It is the absolute value of any number multiplied with it on the trigonometric function. The height from the centre line to the peak (or trough) is called amplitude. You can also measure the height from highest to lowest points and then dividing it by 2.
How far the function is shifted from the usual position horizontally is called a Phase.
Similarly, for the cosine function we can use the formula a cos (bx – c) + d.
The angles of sine, cosine, and tangent are the primary classification of functions of trigonometry. And the three functions which are cotangent, secant and cosecant can be derived from the primary functions. Basically, the other three functions are often used as compared to the primary trigonometric functions.
Let us discuss the formulas given in the table below for functions of trigonometric ratios (sine, cosine, tangent, cotangent, secant and cosecant) for a right-angled triangle.
The trigonometric ratio table for six functions like Sin, Cos, Tan, Cosec, Sec, Cot, are:
By now we have known the formulas and values for different angles for all the trigonometric functions. Let us see here the graphs of all the six trigonometric functions to understand the alteration with respect to a time interval.
The six trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant and Cotangent.
