The period of the sine curve is the length of one cycle of the curve. The natural period of the sine curve is 2Ï. So, a coefficient of b=1 is equivalent to a period of 2Ï. To get the period of the sine curve for any coefficient b, just divide 2Ï by the coefficient b to get the new period of the curve.
The Function y = sin -1 x = arcsin x and its Graph: Since y = sin -1 x is the inverse of the function y = sin x, the function y = sin-1x if and only if sin y = x. But, since y = sin x is not one-to-one, its domain must be restricted in order that y = sin -1 x is a function.estrict the domain of the function to a one-to-one region-typically is used (highlighted in red at right) for sin -1 x. This leaves the range of the restricted function unchanged as [-1, 1]. Reflect this graph across the line y = x to get the graph of y = sin x (y = arcsin x), the black curve at right.
