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?

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

That is the part i have the most trouble with. So is the difference between sin and cos just moving the graph over one unit to the right? Or is that only in this case

anonymous · Answer

Oh wait thats not right... Give me a sec to graph them

phi · Answer

we are using radians to measure the angle.

if we draw a circle, and measure the angle from the x-axis
|dw:1393595767990:dw|

notice that x value will be the cos(x)  and the y-value the sin(x)
