Question

2 part question regarding the form A sin (bx+c):

Answer 1

OK, shoot.

Answer 2

Is the form \[A \sin (x + \phi)\]
the same format, but where phi = -c/b

Answer 3

Your question is "Is \[A \sin(x+\phi) = A \sin (bx+c)\]?" Correct?

Answer 4

yes, an answer from yesterday employed phi and I am trying to make sense of it in the format given at the very top.

Answer 5

"but where phi = -c/b" If phi=-c/b, then the statement above is not true.

I'm pretty sure phi only meant an angle, like alpha, theta or beta.

Answer 6

does phi change or is it constant?

Answer 7

if anyting b= 1 and c = phi in the example you give

Answer 8

Yes, Amistre is right.

Answer 9

I am learning that in the y=A sin (bx+c) that A is amplitude, the period is 2(pi)/b and the phase angle (shift) is -c/b...

so if b is 1, then c is phi, all angles.

Answer 10

Let me ask the second question in a new thread so I can award new medals.

Answer 11

Sure, go ahead.
