The solution
Detail solution
Given the equation
$$3 \sin{\left(x \right)} = 0$$
- this is the simplest trigonometric equation
We get:
$$3 \sin{\left(x \right)} = 0$$
The equation is transformed to
$$\sin{\left(x \right)} = 0$$
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
$$3 \sin{\left(x \right)} = 0$$
- this is the simplest trigonometric equation
with the change of sign in 0
We get:
$$3 \sin{\left(x \right)} = 0$$
Divide both parts of the equation by 3
The equation is transformed to
$$\sin{\left(x \right)} = 0$$
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
