domain 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.
What is the domain, range, and period of y= sin x + 1
What is the domain, range, and period of y= -cos x
Can someone please help?
