Q: I have a home test. I already did but I do not know if I did it right. I was wondering if you could do and show me how you did it so I can learn. I just want to know because I missed so many days of school because of legal problems.
A: Your explanation makes no sense.
You said you did the test at home, but you want to learn how. How could you do if you do not know how?
1.
Solve cos x − 1 = 0 on the interval 0 ≤x ≤ π/2.
x = π/3
x =0
x = π/6
x = π/4
Question 2: Monster
1) cos x − 1 = 0 on the interval 0 ≤x ≤ π/2
cos x = 1
Cosine is 1 when the angle is 0, so x = 0.
2) This is just a right triangle. Drawing the picture should help. If you draw it, the side opposite θ is 10,
