## Amplitude of Sine Functions – Formulas and Examples

All sine functions have an amplitude and a period. The amplitude is the distance between the centerline of the function and the maximum or minimum point of the function. We can also consider the amplitude as the vertical distance between the sinusoidal axis and the...

## Period of the Sine Function – Formulas and Examples

The period of the sine function is 2π. This means that the value of the function is the same every 2π units. Similar to other trigonometric functions, the sine function is a periodic function, which means that it repeats at regular intervals. The interval of the sine...

## Graph of Sine with Examples

The graph of the sine function is characterized by being a function that has a period of 2π. This means that the function repeats itself every 2π and extends indefinitely in both the positive and negative directions. Therefore, the domain of the function is equal to...

## Sine of an Angle – Formulas and Examples

The sine of an angle is a function that relates to the sides of a right triangle. Specifically, the sine is found by taking the side that is opposite the angle and dividing it by the hypotenuse of the triangle. Outside the triangle, the sine function can be used to...

## Amplitude of Cosine Functions – Formulas and Examples

The amplitude along with the period are characteristics of all cosine functions. The amplitude of a function is defined as the distance from the central axis to the maximum or minimum value of the function. In the case of the sine and cosine functions, the central...
