Trig Functions Test
Part 2 – With calculators
Find the exact value of each of the remaining trigonometric
functions.
11. sin q = -4/5 , cos q > 0
12. cos q = -3/5, sin q < 0
13. tan q = 12/5 , sin q < 0
14. cot q =
12/5, cos q
< 0
15. sec q = -5/4, tan q < 0
16. csc q = -5/3, cot q < 0
Find the exact value of each expression.
17. sin-1 1
18. tan-1 (-…3)
19. sec ( tan-1 ((…3) / 3))
20. The minute hand of a clock is 8 inches long. How far
does the tip of the minute hand move in 30 minutes? How far does it move in 20
minutes?
BONUS (show work on the back):
The radius of each wheel of a car is 16 inches. At how may
