    Trignometric identities question

    I still don't really understand... I tried it marlon's way 2p^2+p-1=0 2p^2+p=1 2p+p=1 (squareroot) 3p=1 p=1/3 Is the right?

    Solve a Short Parabola Question with 2π/3 Period | Example Problem

    I accidently made the assumption is was a parabola because the question asks for amplitude, period, phase shift, domain, range, and vertical shift (but I know you can do this for a sine graph to) Do you know how to graph it on a graphing calculator? I do not recall how to solve this type of...
