Graph of sine curve and its variation | Connection b/w sine curve and breathing cycle | Part - 1

In this video, we have discussed how to sketch the sine curve and its possible variation.

Examples Discussed:
Determine the amplitude of y = sin x. Then graph y = 1/2 sin x and y = sin x.

Determine the amplitude of y = —2 sin x. Then graph y = sin x and y = -2 sin x

Determine the amplitude and period of y = 3 sin 2x. Then graph the function.

Determine the amplitude, period, and phase shift of y = 4 sin(2x - 2pi/3)
graph one period of the function.
