what are the basic graphs of sine and cosine?
what are the basic graphs of sine and cosine?
They are similar:
They are similar:
-They both go from -1 to 1 in the y-direction
-They both go from -1 to 1 in the y-direction
-They are both periodic (repeating)
-They are both periodic (repeating)
-sin(x) starts at (0, 0)
-sin(x) starts at (0, 0)
-cos(x) starts at (0, 1)
-cos(x) starts at (0, 1)
So, what happens if the function isn't "basic"?

There are four ways that a sine or cosine function can shift:
