y=2sinx
what is the effect of 2 in the equation above?
someone pls help me with this..
The two doubles the amplitude of the graph. This means that your range is now
It also means that your graph goes from -2 to +2 in the same "space" (which is in this case)
Edit: More generally will have a range of and will go from to in radians.
See the attached graph for how this would look, green is 2sin(x) and blue is sin(x) for comparison
