___ sin(x)*tan(x) - -\/ 3 *sin(x) = 0
$$\sin{\left(x \right)} \tan{\left(x \right)} - - \sqrt{3} \sin{\left(x \right)} = 0$$
Detail solution
Given the equation:
$$\sin{\left(x \right)} \tan{\left(x \right)} - - \sqrt{3} \sin{\left(x \right)} = 0$$
Transform
$$\sin{\left(x \right)} \tan{\left(x \right)} - - \sqrt{3} \sin{\left(x \right)} = 0$$
$$\left(\tan{\left(x \right)} + \sqrt{3}\right) \sin{\left(x \right)} = 0$$
Consider each factor separately
$$\tan{\left(x \right)} + \sqrt{3} = 0$$
- this is the simplest trigonometric equation
Move $\sqrt{3}$ to right part of the equation
with the change of sign in $\sqrt{3}$
We get:
$$\tan{\left(x \right)} = - \sqrt{3}$$
This equation is transformed to
$$x = \pi n + \operatorname{atan}{\left(- \sqrt{3} \right)}$$
Or
$$x = \pi n - \frac{\pi}{3}$$
, where n - is a integer
$$\sin{\left(x \right)} = 0$$
- this is the simplest trigonometric equation
We get:
$$\sin{\left(x \right)} = 0$$
This equation is transformed to
$$x = 2 \pi n + \operatorname{asin}{\left(0 \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(0 \right)} + \pi$$
Or
$$x = 2 \pi n$$
$$x = 2 \pi n + \pi$$
, where n - is a integer
The final answer:
$$x_{1} = \pi n - \frac{\pi}{3}$$
$$x_{2} = 2 \pi n$$
$$x_{3} = 2 \pi n + \pi$$
$$\sin{\left(x \right)} \tan{\left(x \right)} - - \sqrt{3} \sin{\left(x \right)} = 0$$
Transform
$$\sin{\left(x \right)} \tan{\left(x \right)} - - \sqrt{3} \sin{\left(x \right)} = 0$$
$$\left(\tan{\left(x \right)} + \sqrt{3}\right) \sin{\left(x \right)} = 0$$
Consider each factor separately
Step
$$\tan{\left(x \right)} + \sqrt{3} = 0$$

The final answer:
$$x_{1} = \pi n - \frac{\pi}{3}$$
$$x_{2} = 2 \pi n$$
$$x_{3} = 2 \pi n + \pi$$
