Answer 2

Set the inside of the function equal to 0 if sin and π/2 if cos and solve

Question 3

3rd step of calculating zeros

Answer 3

Write zeros as the thing you just solved for +/- the period

Question 4

Do you have to isolate x when finding equilibrium zeros?

Answer 4

No

Question 5

Step 1 of finding max. point

Answer 5

Find period 2π/b

Question 6

Step two of finding max. point

Answer 6

Set the middle equal to the max point on the graph.
Pos A Sin= π/2
Neg A Sin= 0

Pos A Cos= 0
Neg A Cos= π/2
solve for x
