  1. Warm – up 2/14/19 Find the missing measures. Write all answers in radical form. x 30° 30 10 z 45 3 60 y 45 60° y

  2. Learning Target 4 The Trigonometric Functions we will be looking at SINE COSINE TANGENT

  3. The Trigonometric Functions SINE COSINE TANGENT

  4. SINE Pronounced “sign”

  5. COSINE Pronounced “co-sign”

  6. TANGENT Pronounced “tan-gent”

  7. Greek Letter q Prounounced “theta” Represents an unknown angle

  8. hypotenuse hypotenuse opposite opposite adjacent adjacent

  9. Finding sin, cos, and tan.(Just writing a ratio or decimal.)

  10. Find the sine, the cosine, and the tangent of angle A. Give a fraction and decimal answer (round to 4 places). 10.8 9 A 6 Shrink yourself down and stand where the angle is. Now, figure out your ratios.

  11. Find the sine, the cosine, and the tangent of angle A 24.5 Give a fraction and decimal answer (round to 4 decimal places). 8.2 A 23.1 Shrink yourself down and stand where the angle is. Now, figure out your ratios.

  12. Learning Target 5aFinding a side.(Figuring out which ratio to use and getting to use a trig button.)

  13. 20 m 20 55 ) tan x Ex: 1 Figure out which ratio to use. Find x. Round to the nearest tenth. Shrink yourself down and stand where the angle is. Now, figure out which trig ratio you have and set up the problem.

  14. 80 ft 80  ( 72 = ) ) tan x Ex: 2 Find the missing side. Round to the nearest tenth. Shrink yourself down and stand where the angle is. Now, figure out which trig ratio you have and set up the problem.

  15. 283 m x Ex: 3 Find the missing side. Round to the nearest tenth. Shrink yourself down and stand where the angle is. Now, figure out which trig ratio you have and set up the problem.

  16. Ex: 4 Find the missing side. Round to the nearest tenth. 20 ft x

  17. Finding an angle.(Figuring out which ratio to use and getting to use the 2nd button and one of the trig buttons.)

  18. 17.2 9 ) 2nd tan Ex. 1: Find . Round to four decimal places. 17.2 9 Shrink yourself down and stand where the angle is. Now, figure out which trig ratio you have and set up the problem. Make sure you are in degree mode (not radians).

  19. 7 23 ) 2nd cos Ex. 2: Find . Round to three decimal places. 7 23 Make sure you are in degree mode (not radians).

  20. 200 400 ) 2nd sin Ex. 3: Find . Round to three decimal places. 200 400 Make sure you are in degree mode (not radians).

  21. When we are trying to find a sidewe use sin, cos, or tan. When we are trying to find an angle we use sin-1, cos-1,ortan-1.
