it didn't affect the answer here though, since C = 0, but it might in some other question. (or i don't know, maybe in practice it won't make much of a difference, since the value of C may be altered by the way you set up the equation or something)
Good Job though!  |
I see.
B(x -C) = (Bx -BC)
I called "BC" as C
The frequency B remains the same.
Using the B(x -C) is sometimes confusing. Others interpret then that C is the phase angle or horizontal shift, when, in fact, it should be "C/B".
Confucing, is it not?
Should it not be "CB"?
