According to Wikipedia,
The sine wave or sinusoid is a mathematical function that describes a smooth repetitive oscillation.
The formula for the Sine wave is,
A = Amplitude of the Wave ω = the angular frequency, specifies how many oscillations occur in a unit time interval, in radians per second φ, the phase, t = ?
Here ω, is the angular frequency i.e ,
It defines how many cycles of the oscillations are there.
Now let see the frequency,
Frequency is the number of occurrences of a repeating event per unit time
For example, if 100 events occur within 15 seconds the frequency is:
Events = 100; Time = 15; FREQ = Events/Time;
Which means there is total 100 cycles of wave in 15 seconds , am i correct ?
Events = 71; Time = 15; FREQ = Events/Time; W = 2*PI*FREQ; % 2*PI for circular path A = 2 ;
Now what is the use of small 't' ? in the Sine wave equation , what time is it ?
