The solution
Detail solution
Given the equation
$$\sin{\left(x \right)} = 0.8634$$
- this is the simplest trigonometric equation
This equation is transformed to
$$x = 2 \pi n + \operatorname{asin}{\left(0.8634 \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(0.8634 \right)} + \pi$$
Or
$$x = 2 \pi n + 1.04197038243603$$
$$x = 2 \pi n - 1.04197038243603 + \pi$$
, where n - is a integer
$$\sin{\left(x \right)} = 0.8634$$
- this is the simplest trigonometric equation
This equation is transformed to
$$x = 2 \pi n + \operatorname{asin}{\left(0.8634 \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(0.8634 \right)} + \pi$$
Or
$$x = 2 \pi n + 1.04197038243603$$
$$x = 2 \pi n - 1.04197038243603 + \pi$$
, where n - is a integer
