**Steve**, Friday, February 3, 2012 at 3:08pmdomain of sin(x) and cos(x) is all reals

period of sin(x) and cos(x) is 2pi

range of sin(x) and cos(x) is [-1,1]

sin(x)+1 is just like sin(x) but raised +1 on y, so all that's changed is the range: [0,2]

-cos(x) is just cos(x) reflected in the x-axis, so nothing is changed.
