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

Sine 3.3 degrees is about 0.057564. Sine 3.3 radians is about -0.157746. Sine 3.3 grads is about 0.051813.
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.

A sine wave or sinusoid, forms an oscillation, or is oscillating in a regular up and down movement.

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.
sine(15 degrees) = 0.25882 (rounded)
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.

One. Exactly one.
