What is co·sine?
(kō'sīn') n. ( Abbr. cos ) In a right triangle, the ratio of the length of the side adjacent to an acute angle to the length of the hypotenuse. The abscissa at the endpoint of an arc of a unit circle centered at the origin of a Cartesian co... Read More »

A "zero of a function" is a point where the dependent value (usually, Y) is zero. In the function f(x) = x2 - 2, for example, there are zeroes at -1.414 and +1.414. The zeroes of the sine function are at all integer multiples of pi, i.e. 0,...
