Part 1: Using complete sentences, compare the key features and graphs of sine and cosine. What are their similarities and differences? Part 2: Using these similarities and differences, how would you transform f(x) = 4 sin(2x - π) + 3 into a cosine function in the form f(x) = a cos(bx - c) + d?

    can you compare the sin(x) with the cos(x)?

    we are using radians to measure the angle. if we draw a circle, and measure the angle from the x-axis |dw:1436458116835:dw| notice that x value will be the cos(x) and the y-value the sin(x)

    now as you turn counter-clockwise, the sin x gets bigger (until we reach pi/2 i.e. 90º i.e. pointing straight up) and cos x gets smaller. if we plot the numbers we get the graph I posted up above. notice that when x reaches 2 pi we went around the circle, and everything repeats...

    the *only* difference between sin x and cos x is that sin x is shifted by pi/2 as compared to cos x (or vice versa)
