  8. if t is any real number, what is cos t?
    cos t = x
  9. if t is any real number, what is sin t?
    sin t = y
  10. if t is any real number, what is tan t?
    tan t = y/x, x cannot equal 0
  11. if t is any real number, what is csc t?
    csc t = 1/y, y cannot equal 0
  12. if t is any real number, what is sec t?
    sec t = 1/x, x cannot equal 0
  13. if t is any real number, what is cot t?
    cot t = x/y, y cannot equal 0
  14. when P(x,y) are the points belonging to t, what are the corresponding trig functions on the unit circle?
    P(x,y) = (cos t, sin t)
  15. What is the relationship between cos t and cos (-t)?
    • they are always equal to each other.
    • cos t = cos (-t)
  16. What is the relationship between sin t and sin (-t)?
    • they are always equal to each other.
    • sin t = sin (-t)
  17. What is the relationship between sin t and sin (t + 2pi)?
    • they are always equal to each other
    • sin t = sin (t + 2pi)
  18. What is the relationship between sin t and sin (t + pi)?
    they are always opposite to each other
  19. What is the relationship between tan t and tan (t + pi)?
    • they are always equal to each other
    • tan t = tan (t + pi)
  20. What is the sum of (cos t)^2 + (sin t)^2?
    (cos t)^2 + (sin t)^2 = 1
  21. What are the radian values for 30, 45, and 60 degrees?
    • 30 degrees = pi/6
    • 45 degrees = pi/4
    • 60 degrees = pi/3
