I would assume you know how to sketch
y = sinx
for y = 2 sinx, your amplitude is now 2 instead of 1
for y = sin 2x, amplitude is 1, but you will have 2 complete sine curves from 0 to 360
on the same set of axes: (0 degrees is greater than or equal to x and x is less than or equal to 360 degrees)
(a) sketch the graphs of y= sin degrees ,y=2sinx degrees and y=sin2x degrees
