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

Question

anonymous · Answer

OK, shoot.

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

"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.

does phi change or is it constant?

amistre64 · Answer

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

anonymous · Answer

Yes, Amistre is right.

anonymous · Answer

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.

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