# Thread: Algebracially, Find values for a, b, and h

1. ## Algebracially, Find values for a, b, and h

a sin (b(x-h)) = 2sin3x-5cos3x

2. ## Re: Algebracially, Find values for a, b, and h

These formulas can help.

3. ## Re: Algebracially, Find values for a, b, and h

i looked at all of the formulas and the linear formula that would apply is for: a sin(x)+b cos(x) i need it for: a sin(x) - b cos(x)

What conditions on a and b do those formulas have? Do they requite that b be positive? Do you get my point?
