Question

Consider the graph of the cosine function.
a) Find the period and amplitude of the cosine function.
b) At what values of Ө for 0≤Ө≤π/2 do the maximum value(s), minimum value(s), and zeroes occur?

Answer 1

Would the period be \(\Large\frac{\pi}{3}\) and the amplitude be 2?

Answer 2

I'm not quite sure what the period is actually....

Answer 3

I agree with your amplitude. The period is the distance between two points that are the same (e.g. maximum to maximum).

Answer 4

I don't think it's pi/3.

Answer 5

I know that part lol I just noticed it gives it to us in part b.

Answer 6

\[\frac{\pi}{2}\]

Answer 7

I agree.

Answer 8

I'm not sure about part b though. Any thoughts on how I figure it out?

Answer 9

max occurs at 0 and pi/2

Answer 10

min: pi/4

Answer 11

I have to show my work...it's a portfolio item I'm working on :/

Answer 12

How do I find that?
