Verified Answer :

The general form of the equation is  acot (bx−c)+d to find the variables used to find the amplitude, period, phase shift, and vertical shift where a=1, b=π/4, c=0 and d=0
Period is pi/b or equal to 4. 

The vertical asymptote is 4pi n where n is integer.

Answer:

Refer the attached figure.

Vertical asymptote \(x=4+4n\)

Step-by-step explanation:

Given : Function  \(y=\cot (\frac{\pi}{4}x)\)

To find : Sketch the given function and find the vertical asymptotes of the function ?

Solution :

Function  \(y=\cot (\frac{\pi}{4}x)\)

Sketch the function on the graph.

Refer the attached figure.

Now, Vertical asymptote is defined as

On a graph, a line which is approached by a curve but never reached.

i.e. on different values of x y tends to infinity.

When we see the graph the vertical asymptote of the function is given by

\(x=4+4n\) for n=0,1,2,3...
