The solution
Detail solution
Given the equation
$$\tan{\left(x \right)} = \frac{4}{5}$$
- this is the simplest trigonometric equation
This equation is transformed to
$$x = \pi n + \operatorname{atan}{\left(\frac{4}{5} \right)}$$
Or
$$x = \pi n + \operatorname{atan}{\left(\frac{4}{5} \right)}$$
, where n - is a integer
$$\tan{\left(x \right)} = \frac{4}{5}$$
- this is the simplest trigonometric equation
This equation is transformed to
$$x = \pi n + \operatorname{atan}{\left(\frac{4}{5} \right)}$$
Or
$$x = \pi n + \operatorname{atan}{\left(\frac{4}{5} \right)}$$
, where n - is a integer
