The solution
Detail solution
Given the equation
$$\tan{\left(x \right)} = -3$$
- this is the simplest trigonometric equation
This equation is transformed to
$$x = \pi n + \operatorname{atan}{\left(-3 \right)}$$
Or
$$x = \pi n - \operatorname{atan}{\left(3 \right)}$$
, where n - is a integer
$$\tan{\left(x \right)} = -3$$
- this is the simplest trigonometric equation
This equation is transformed to
$$x = \pi n + \operatorname{atan}{\left(-3 \right)}$$
Or
$$x = \pi n - \operatorname{atan}{\left(3 \right)}$$
, where n - is a integer
