Question

Please Help. Find a formula for the trigonometric function graphed below. Use x as the independent variable in your formula.

Answer 1

Acos(Bx+C) i know that A is 0.6. I am trying to find B

Answer 2

anybody there?

Answer 3

@wio

Answer 4

What is the period?

Answer 5

pi/6

Answer 6

correct?

Answer 7

@tkhunny any idea?

Answer 8

It's taking too long. I'll give you one for free. You show us another one.

1) It is not possibe with the given inforamtion. We are left to spectulate what we THINK are exact values. It LOOKS like there is a trough at 0, pi/12, and pi/6, but IS there? It's just not perfectly clear. It LOOKS like the range it [-0.6,+0.6], but IS it? It's just not clear.

2) Peak at x = 0. This calls for a cosine with NO phase shift.

y = ___ cos(___x)

Amplitude = 0.6

y = 0.6*cos(___x)

Period: pi/12 ==> 2pi/Something = pi/12 ==> Something = 24

y = 0.6*cos(24x)

Answer 9

thank you very much.

Answer 10

Pay up!! Where's yours?

Answer 11

* I meant "peak", not "trough".

Answer 12
