. We write the ordered pairs of this function as ( q , P( q )). Let q be any real number and let the co-ordinates of P( q ) be (x,y). We define the cosine function of q (written as cos q ) and sine function of q (written as sin q ). In term of the co-ordinate..

.e., the displacement on either side of the equilibrium position is confined within well-defined limits. The trigonometric functions namely, the sine and cosine functions are periodic as well as bounded. These functions are called harmonic functions..

- 1 x cosine inverse x is q and write cos - 1 x = q . In particular, For practical purposes, only principal values of cos - 1 x are considered. cos - 1 x is a function of x with domain [-1,1] and range [0, p ]. The graph of cos - 1 x is as shown in the fig..

. The sum of the two sine waves This can be put in a more useful form by using the relation for the sum of two cosines from trigonometry: is the modulation functions or "envelope" (the outer curve in the above figure). In this case, the modulation function ha..
