sin(a) is the y value in the unit circle of angle a (see diagram) So if we take sin(a), we will always be on the other side of the y axis. (a means 360a°) Therefore is sin(a) is positive, sin(a) will be the negative value of sin(a) and the opposite applies

Also we can use the sum/diff formula for sin sin(a) = sin(0a) = sin(0)cos(a)cos(0)sin(a) = 0*cos(a)1*sin(a) = sin(a)
