To do part A, first convert all the radians to degrees. To convert radians to degrees, multiply by 180degrees/2pi
To do part b, you need to have done part a. Then you need to find the angle closest to the x-axis. For example, the reference angle for 120 degrees would be 60 since the reference anglle is in the second quadrant.
To do part c, you need to have graphed the angle and draw a right triangle using the reference angle and the special triangle relationships to find the value for the questions. 30-60-90 triangles have a side relationship of 1-sqrt3-2
And, 45-45-90 triangle have a relationship of sqrt2-sqrt2-2 That is the same thing as 1-1-sqrt2
To do part d, you need to know that in the first quadrant everything is positive. In the second quadrant, only sin and cosecant are positive. In the third quadrant, only tan and cotangent are positive. In the fourth quadrant, only cos and secant are poitive.
