## Homework Statement

Determine a sine function, f, and a cosine function, g, such that y = sqrt2sin(pi(x-2.25))

can be written in the form of f-g.

## Homework Equations

(f-g)(x) = f(x) - g(x)

## The Attempt at a Solution

I think that you should sub in the y= equation so that you get:

sqrt2sin(pi(x-2.25)) = f(x) - g(x)

and then sub in any X value? I really don';t know
