The period of y=sin(x) is 2*pi, so sin(x) repeats every 2*pi units. sin(5x) repeats every 2*pi/5 units. In general, the period of y=sin(n*x) is 2*pi/n.

The period is the length of x over which the equation repeats itself. In this case, y=sin x delivers y=0 at x=0 at a gradient of 1. y next equals 0 when x equals pi, but at this point the gradient is minus 1. y next equals 0 when x equals 2pi, and at this point the gradient is 1 again. Therefore the period of y=sinx is 2pi.
y = sin(-x)Amplitude = 1Period = 2 pi
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
-4
If: 3x+y = 4 and x+y = 0 Then: x = 2 and y = -2
