For the following exercises, graph the functions for two periods and determine the amplitude or stretching factor, period, midline equation, and asymptotes.
f(x) = 1/4 sin x
Periodic function:
A periodic function is a function that repeats its value over a fixed interval. The fixed interval is called as period of the function. Mathematically it is represented as
f(x + P) = f(x)
Sine function:
A sine function is a trigonometric function representing ratio between opposite side to hypotenuse. It is an odd function with period 2π.
A general form of sine function is
y = Asin(Bx – C) + D
Where P is the period of the function f(x).
In this case the sine function is
f(x) = 1/4sinx
Comparing with the general form the amplitude is
|A| = 1/4
Period of the function is
P = 2π/|B|
= 2π
Since, D = 0, the midline equation is
y = 0
There are no asymptotes.
Amplitude of the function is 1/4.
Period of the function is 2π.
Mid line of the function is y = 0.
Graph is plotted as follows:
