Question

Sine function is defined Sine: R [-1,1] is invertible . justify?​

Answer 1

Answer:

sine function is a function with R as its domain and [−1, 1] as its range. We write y = sin x and y = sin−1x or y = arcsin(x) to represent the sine function and the inverse sine function, respectively. Here, the symbol −1 is not an exponent. It denotes the inverse and does not mean the reciprocal.

We know that sin ( x + 2π ) = sin x is true for all real numbers x . Also, sin ( x + p) need not be equal to sin x for 0 < p < 2π and for all x . Hence, the period of the sine function is 2 π
