    More Cartesian to Parametric Form

    Convert from cartesian to parametric equation form?

    y = sinx + cosx

    This is ridiculous- if the problem is that you do not know what "parametric equations" are, look it up! If you do then make some effort yourself.

    Re: More Cartesian to Parametric Form

    Here is my effort.

    y = sinx + cosx

    x = cost
    y = sint

    Is this correct?

    No, it's not! Do you realize that you are claiming that sin(t)= sin(cos(t))+ cos(cos(t))?

    do you really not see that it's just

    $\{t,\sin(t)+\cos(t)\}$
