Y=1/5x-2
Hope this helped :)
We have to find the domain of y = cotx
We know that cotx = cos
x / sinx
And also when sinx becomes zero cotx becomes undefined
And again we know that value of cosx and sinx can be between -1 to 1
But value of cotx can lie in between -∞ to +∞
Just for example cot30 is cos30 / sin30
= √3/2/1/2 = √3
Therefore domain of cotx is x
x ∈ R , x ≠ πn for any integer n
I'm guessing the function is

which, split into partial fractions, is equivalent to

Recall that for
we have

With some rearranging, we find

valid for
, or
, and

valid for
, or
.
So we have



Taken together, the power series for
can only converge for
, or
.
