1. 1. 7.4 Inverse Trig Functions Day 3Psalm 22:19But you, O LORD, be not far off; O my Strength, come quicklyto help me.
2. 2. An alien spacecraft is ﬂying at 3000 feet and isapproaching a photographer. The photographer wants totake a picture of it when it is 4000 feet away. At whatangle should the camera be set?
3. 3. An alien spacecraft is ﬂying at 3000 feet and isapproaching a photographer. The photographer wants totake a picture of it when it is 4000 feet away. At whatangle should the camera be set? 4000 3000 θ
4. 4. An alien spacecraft is ﬂying at 3000 feet and isapproaching a photographer. The photographer wants totake a picture of it when it is 4000 feet away. At whatangle should the camera be set? 4000 3000 θ −1 3000 sin θ = 4000
5. 5. An alien spacecraft is ﬂying at 3000 feet and isapproaching a photographer. The photographer wants totake a picture of it when it is 4000 feet away. At whatangle should the camera be set? 4000 3000 θ −1 3000 sin θ = 4000 θ ≈ 48.6°
6. 6. Inverse csc, sec, cot ...
7. 7. Inverse csc, sec, cot ... Graph y = csc x and compare to what I have ... −1
8. 8. Inverse csc, sec, cot ... Graph y = csc x and compare to what I have ... −1 ⎛ 1 ⎞ −1 y = sin ⎜ ⎟ ⎝ x ⎠
9. 9. Inverse csc, sec, cot ... Graph y = csc x and compare to what I have ... −1 ⎛ 1 ⎞ −1 y = sin ⎜ ⎟ ⎝ x ⎠ Turn to page 556; compare the book graphs vs. ours.
10. 10. Inverse csc, sec, cot ... Graph y = csc x and compare to what I have ... −1 ⎛ 1 ⎞ −1 y = sin ⎜ ⎟ ⎝ x ⎠ Turn to page 556; compare the book graphs vs. ours. They have used different domains than our calculator ... all three graphs are correct but simply different than what we get.
11. 11. Graph y = sec x and compare to what I have ... −1
12. 12. Graph y = sec x and compare to what I have ... −1 ⎛ 1 ⎞ −1 y = cos ⎜ ⎟ ⎝ x ⎠
