EL-9600/9400 Graphing Calculator

Calculating Simple Harmonic Oscillation

Enter period, amplitude and time to calculate displacement at specified time, acceleration, angular velocity, and velocity. Also, display the changes during the entered time period on a graph.

Calculation
angular velocity : ω =	2π	displacement : x = A+ sin (ω t)
	T	velocity : v = A+ ω+ cos (ω t)

T : period [sec]
		0	2π
ω : angular velocity [rad/sec]
