      sin(x + y) = sin(x)cos(y) + cos(x)sin(y). It is then easily derived that. sin(x - y) = sin(x)cos(y) - cos(x)sin(y). Or more generally,. sin(x ± y) = sin(x)cos(y) ± cos(x)sin(y).

        What is the domain of the cosine function?
          The sin and cos functions have a period of 2π radians and the tan function has a period of π radians. Domain and range: From the graphs above we see that for both the sin and cos functions the domain is all real numbers and the range is all reals from −1 to +1 inclusive.
