Question 1100228: Can someone help me? Thank you.
Function f(x)= sin X is neither one to one nor onto function. Why?
Determine restrictions on the domain and co-domain so that f(x)=sin x is invertible.

One to one : Since the sin function is periodic, there are multiple values of x for a given value of y. Therefore it cannot be one to one.
.
.
.
Onto : There is no x in the domain that will give a value of f(x) such that . So it's not onto.

If we restrict the domain to [,] and restrict the co-domain to [,].
