\/ 3*cot(x)  = 1
3cot(x)=1\sqrt{3 \cot{\left(x \right)}} = 1
Detail solution
Given the equation
3cot(x)=1\sqrt{3 \cot{\left(x \right)}} = 1
transform
3cot(x)1=0\sqrt{3} \sqrt{\cot{\left(x \right)}} - 1 = 0
3cot(x)1=0\sqrt{3 \cot{\left(x \right)}} - 1 = 0
Do replacement
w=cot(x)w = \cot{\left(x \right)}
Given the equation
3w1=0\sqrt{3} \sqrt{w} - 1 = 0
Because equation degree is equal to = 1/2 - does not contain even numbers in the numerator, then
the equation has single real root.
We raise the equation sides to 2-th degree:
We get:
(3w)2=12\left(\sqrt{3 w}\right)^{2} = 1^{2}
or
3w=13 w = 1
Divide both parts of the equation by 3
w = 1 / (3)

We get the answer: w = 1/3

The final answer:
w1=13w_{1} = \frac{1}{3}
do backward replacement
cot(x)=w\cot{\left(x \right)} = w
substitute w:
