A function that depends on the value of an angle. One way to define it is with a unit circle (a circle with center in the coordinate origin, and radius of 1). To the right is zero, from there, a positive angle is counterclockwise. In this case, the sine is simply the y-coordinate, and the cosine is the x-coordinate of the point on the circle where the ray of the angle crosses the circle. The value of the sine (and cosine) obviously depends on the angle - that's why it is considered a "function".

Sine, cosine, tangent, cotangent, cosecans, and secans can also be defined via right triangles; for more details see here: http://en.wikipedia.org/wiki/Sine#Sine.2C_cosine_and_tangent

No, the sinus node in the heart is a group of cells that generate electrical impulses to control heart rhythm. It is not related to the sine function in mathematics, which is a trigonometric function used to represent oscillatory motion.

Sine does not converge but oscillates. As a result sine does not tend to a limit as its argument tends to infinity. So sine(infinity) is not defined.

Trigonometry is a mathematical tool that is part of various other forms of mathematics and is used in all sorts of science and engineering; for example, the sine function in trigonometry turns out to be applicable to sine waves that are formed by alternating electrical currents which are used to power your computer which is the basic tool that you use in information technology.
