The solution
Detail solution
Given the equation
$$\cot{\left(x \right)} = 0$$
- this is the simplest trigonometric equation
We get:
$$\cot{\left(x \right)} = 0$$
This equation is transformed to
$$x = \pi n + \operatorname{acot}{\left(0 \right)}$$
Or
$$x = \pi n + \frac{\pi}{2}$$
, where n - is a integer
$$\cot{\left(x \right)} = 0$$
- this is the simplest trigonometric equation
We get:
$$\cot{\left(x \right)} = 0$$
This equation is transformed to
$$x = \pi n + \operatorname{acot}{\left(0 \right)}$$
Or
$$x = \pi n + \frac{\pi}{2}$$
, where n - is a integer
