cos sinusoidal function Sine and cosine are written using functional notation with the abbreviations sin and cos Often if the argument is simple enough the function value will be written without parentheses as sin rather than as sin Each of sine and cosine is a function of an angle which is usually expressed in terms of radians or degrees Except where explicitly stated otherwise this article assumes that the angle is measur
The basic sine and cosine functions have a period of 2 pi The function sin x is odd so its graph is symmetric about the origin The function cos x is even so its graph is symmetric about the y axis The graph of a sinusoidal function has the same general shape as a sine or cosine function The term sinusoidal is used to describe a curve referred to as a sine wave or a sinusoid that exhibits smooth periodic oscillation Sinusoids occur often in math physics engineering signal processing and many other
