Question 1035982: 1.a) On the same set of axes, sketch and label graphs of y= sin (1/2)x and y= 2 cos x as x varies from 0 to 2 pi radians.
b) Using the same set of axes, sketch the reflection of y= sin (1/2)x in the line y= -1.
Thank you for helping me out. I really dont understand the whole thing.><

You can put this solution on YOUR website!
.a) On the same set of axes, sketch and label graphs of y= sin (1/2)x and y= 2 cos x as x varies from 0 to 2 pi radians.
Graph of y = sin(x/2)
graph%28400%2C400%2C-6%2C6%2C-2%2C2%2Csin%28x%2F2%29%29
-------
Graph of y = 2cos(x)
graph%28400%2C400%2C-6%2C6%2C-2%2C2%2C2cos%28x%29%29
----------------------
b) Using the same set of axes, sketch the reflection of y= sin (1/2)x in the line y= -1.
Flip each of the graphs over the line y = -1
------
Each point (x,y) would become the point (x,-1-(y+1)) = (x,-y)
