Will fan and give medals!
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) = 2 sin(2x  π) + 3 into a cosine function in the form f(x) = a cos(bx  c) + d?
PLEASE HELP ??

Best ResponseYou've already chosen the best response.0That's the part i already sort of understand, I just need to figure out how to apply it exactly to the second part of the question :L

Best ResponseYou've already chosen the best response.0A sine function on a graph is the same as its cosine form, merely moved over π/2 units to the right, because cos (t) = sin (t + π/2). ^that's what i have so far

Best ResponseYou've already chosen the best response.0Figured it out myself. For others with the same question in the future: f(x) = 2 sin(2x  π) + 3 f(x) = 2 cos(2x  π) + 3 f(x) = 2 cos(2x  π  π/2) + 3 f(x) = 2 cos(2x  3π/2) + 3
