1a)The domain is the possible x values for the function which is given as

$0\leq x\leq360$

1b) The range is the possible y values for the function which is given as

$-1\leq y\leq1$

2) The value of x at the maximum point is the angles that correspond with "1" on the y-axis.

$x=0^0\text{ and 360}^0$

3) The value of y at the minimum point is the angle that corresponds with "-1" on the y-axis.
