I think the phase shift is positive, but everything else looks correct

anonymous · Answer

I was thinking it would be but I just wasn't sure c: thank you n.n

jim_thompson5910 · Answer

you're welcome

I'm reading that the general form is y = A*tan(Bx - C) + D

where the phase shift is  p = C/B, so that's why I'm thinking it's positive

anonymous · Answer

But wouldn't the negative override the positive making the phase shift negative?

jim_thompson5910 · Answer

well y=tan[3θ - 3/4π] -5 means that B = 3 and C = 3/4π

So

p = C/B

p = (3/4π)/3

p = π/4

ohhh okai I see what you mean
