Determining Ordered Pairs for Special Trigonometric Angles

Any angle that is a multiple of , has an ordered pair that comes from the Trig circle. If the value of the angle does not fall between 0 and 2, then you must find the angle between 0 and 2 that occupies the same position. . but.

  1. Any angle that is a multiple of , has an ordered pair that comes from the Trig circle. If the value of the angle does not fall between 0 and 2, then you must find the angle between 0 and 2 that occupies the same position.  but under the wrapping function where f(t) = (x,y). This means that the ordered pair for is the same as the ordered pair for .  If you need to find the ordered pair for you can use the pair from . Determining Ordered Pairs for Special Trigonometric Angles The ordered pair for both is:

  2. If you need to find the ordered pair for you can use the ordered pair directly from the unit circle that you already know. (0,1) =  0 (1,0) (-1,0) 2 (1,0) (0,-1)

  3. If you need to find the ordered pair for you must first realize that it is not one of the angles that fall between 0 and 2. For this reason you need to find an angle between 0 and 2 that occupies the same position on the unit circle. STEP 1: Find the multiples of 2 that falls between. STEP 2: Subtract the lower multiple from . It falls between 2 and 4. It falls between2and 4. It falls between2and 4. It falls between2and 4.

  4. (0,1)  0 (1,0) (-1,0) 2 (1,0) (0,-1) STEP 3: Locate the angle that is between 0 and 2 on the unit circle.

  5. If you need to find the ordered pair for you must first realize that it is not one of the angles that fall between 0 and 2. For this reason you need to find an angle between 0 and 2 that occupies the same position on the unit circle. STEP 1: Find the multiples of 2 that falls between. STEP 2: Subtract the lower multiple from . Quadrant III It falls between -10 and -8. It falls between -10 and -8. It falls between -10 and -8. It falls between -10 and -8. It falls between -10 and -8. STEP 3: Locate the angle that is between 0 and 2 on the unit circle.

  6. That's all Folks!
