Homework Help: Find the points of intersection of the curves y=2sin(x-3) and y=-4x^2+2?

  1. Sep 4, 2011 #1
    Can someone do it without using a graphing calculator? The question specifically states not to use "Trace". I don't understand how to do it algebraically, and I'd love it if someone could teach me. Please and thanks!

    Well you can't solve it algebraically, you can solve it using a numerical method or if you use approximations or maybe some special function (which I am most likely unfamiliar with).

    A numerical method? Like, plugging in numbers? Sorry I'm lost.

    You can use iterative methods which essentially like guessing but the iterations would converge to the points you want to a certain degree of accuracy.
