All you can do is follow the instructions. What is it asking you to do?
. . . ........... .Sin . . .Tan. . . Cos. . . Cot. . . Sec. . . Csc
>>>>>>>>>>>>
5pi/4 = 3.93 . . 0.069 . . 0.069 . . 0.998 . etc
2pi/3 = 2.09
5pi/6 = 2.61
7pi/4
Let your calculator do the work

5pi%2F4, converted to degrees = 225
sin+%28225%5Eo%29 has a reference angle of 45%5Eo, but is in the 3rd quadrant, where sin is < 0 (negative).
Therefore, sin+%28225+%5Eo%29 = -+sin+%2845%5Eo%29 = highlight_green%28-+sqrt%282%29%2F2%29. This is the EXACT VALUE of sin+%285pi%2F4%29. Follow this and try to do the rest.
You can also use the UNIT CIRCLE to determine the EXACT VALUES of all of the above.

They are angles.
