Need help with trigonometry work I've been assigned two questions due tomorrow, and I don't have much of an idea how to do them. 1. Tyler said that one cycle of a cosine curve has a maximum value at (pi/4 , 5) and a minimum value at (5pi/4 , -5). The equation of the curve is y = 5 cos (2x - pi/2). Do you agree with Tyler? Explain why or why not. 2. Is the graph of y = sin 2(x + pi) the same as the graph of y = sin2x ? Explain why or why not. Edit: I need to write a paragraph explaining each ._.
