Homework Statement
Determine a sine function, f, and a cosine function, f, such that y= √2 sin (π(x-2.25)) can be written in the form of f-g.
Homework Equations
The Attempt at a Solution
well.. i know that:
= sinx - cosx
= sinx - (-sin(π/2-x))
= √2 sin(x + π/4)
that's as close i can get it is there an algebraic way to determine this?
thank you!
