Register free for online tutoring session! I dont know how to type cos^2(x)- sin^2(x) into matlab. I think it is cos(x).^2 - sin(x).^2. Also I know the interval is typed out [-2*pi, 2*pi} but I dont understand what the question means by saying using 100 points in the domain 2020-02-13 A simple proof of the very important and useful trigonometry Identity sin^2(x) + cos^2(x) = 1 is shown.
