Homework Help: Rotation os axes confusing me.

  1. Dec 16, 2005 #1
    Hey guys,

    This is my first post, and I spent a lot of time trying to figure this one out and I am totally stumped! Two of my classmates got different answers, and no matter how many ways i work this problem out, I still get the same answer.

    Also, forgive me if my mistake is really simple because at this time last year I was in a pre-algebra class. Now, I'm in precalculus and managing to get an A, but I still make arithmetic mistakes at times.

    I hope this attachment works right.

    G'day, Beeza.

    Your work is great and I agree with you.

    Here's what the tilted parabola looks like with the new axes and the untilted parabola.

    Thanks for the confirmation Unco! I was hoping that I wasn't crazy:surprised

    I'm sure I'll be posting more questions this spring--when I take Calculus1.
