$y=3\cos(\pi x-2)+5$

ok I think these are the plug ins we use

$Y=A\cos\left[\omega\left(x-\dfrac{x \phi}{\omega} \right)\right]+B $

or

$A\cos\left(\omega x-\phi\right)+B$

**A**=amplitude

**B**=

**VS**or veritical shift

$

**T**= \dfrac{2\pi}{\omega-\phi}$

$

**PS**= 0$ assumed here

ok just want to see if I have these plug in eq right, different books use different symbols
