They do not. A sine graph, for example, goes on oscillating forever.

The sine of an angle can never equal 2 because the sine function, defined as the ratio of the length of the opposite side to the hypotenuse in a right triangle, has a range of values between -1 and 1. This means that for any angle, the sine value will always fall within this interval, making it impossible for sine to equal 2. Therefore, there are no angles for which the sine function outputs a value of 2.
Sine 3.3 degrees is about 0.057564. Sine 3.3 radians is about -0.157746. Sine 3.3 grads is about 0.051813.

Both sine and cosine graphs are periodic functions with a periodicity of (2\pi), meaning they repeat their values every (2\pi) radians. They both have an amplitude of 1, oscillating between -1 and 1. Additionally, the sine graph is a horizontal shift of the cosine graph; specifically, the cosine graph can be expressed as the sine graph shifted to the left by (\frac{\pi}{2}) radians. Both graphs exhibit similar shapes, featuring smooth, continuous waves.
The amplitude of a sine function describes the distance from the midline of the wave to its highest or lowest point, not the total distance between the highest and lowest values. Specifically, it is half the distance between the maximum and minimum values of the function. For a sine function, the amplitude is calculated as the absolute value of the coefficient in front of the sine term.
If you mean the sine function, it is dependent on an angle. For example, the sine of an angle of zero degrees is zero; the sine of an angle of 90 degrees is one; for an angle of 180 degrees, the sine is again 0; if you make a graph, you get a curve that looks like a wave. In general, the values the sine function can take are between 1 and -1, inclusive.
The sine of 180 degrees is 0. Remember, the sine value on a unit circle is the y-value. If you find f(pi) in the function f(x)=sin(x), you will get zero as an answer.
If you look at the definition of the sine function in a triangle, you'll discover that the maximum possible value of the sine function is ' 1 ' and the minimum possible value is ' -1 '. There's no angle that can have a sine greater than ' 1 ' or less than ' -1 '. So the absolute value of the sine of anything is always ' 1 ' or less.

If you take instantaneous measurements of an AC voltage you will see it vary from a plus value to a minus value. In typical power applications it is a waveform that looks like a sine wave. Google "sine wave" to see a picture. The frequency for U.S.A. AC is 60 Hz. This means that 60 times a second the voltage will start at zero transition to a maximum positive voltage then go back to zero and to a maximum negative voltage and then back to zero. DC is a constant voltage no matter when you measure. It is simply a straight line when compared to an oscillating AC voltage waveform.
