$$2 \sin{\left(x + \frac{\pi}{3} \right)} = \sqrt{3}$$
Detail solution
Given the equation
$$2 \sin{\left(x + \frac{\pi}{3} \right)} = \sqrt{3}$$
- this is the simplest trigonometric equation
The equation is transformed to
$$\sin{\left(x + \frac{\pi}{3} \right)} = \frac{\sqrt{3}}{2}$$
This equation is transformed to
$$x + \frac{\pi}{3} = 2 \pi n + \operatorname{asin}{\left(\frac{\sqrt{3}}{2} \right)}$$
$$x + \frac{\pi}{3} = 2 \pi n - \operatorname{asin}{\left(\frac{\sqrt{3}}{2} \right)} + \pi$$
Or
$$x + \frac{\pi}{3} = 2 \pi n + \frac{\pi}{3}$$
$$x + \frac{\pi}{3} = 2 \pi n + \frac{2 \pi}{3}$$
, where n - is a integer
Move
$$\frac{\pi}{3}$$
to right part of the equation
with the opposite sign, in total:
$$x = 2 \pi n$$
$$x = 2 \pi n + \frac{\pi}{3}$$
$$2 \sin{\left(x + \frac{\pi}{3} \right)} = \sqrt{3}$$
- this is the simplest trigonometric equation
Divide both parts of the equation by 2
The equation is transformed to
$$\sin{\left(x + \frac{\pi}{3} \right)} = \frac{\sqrt{3}}{2}$$
This equation is transformed to
$$x + \frac{\pi}{3} = 2 \pi n + \operatorname{asin}{\left(\frac{\sqrt{3}}{2} \right)}$$
$$x + \frac{\pi}{3} = 2 \pi n - \operatorname{asin}{\left(\frac{\sqrt{3}}{2} \right)} + \pi$$
Or
$$x + \frac{\pi}{3} = 2 \pi n + \frac{\pi}{3}$$
$$x + \frac{\pi}{3} = 2 \pi n + \frac{2 \pi}{3}$$
, where n - is a integer
Move
$$\frac{\pi}{3}$$
to right part of the equation
with the opposite sign, in total:
$$x = 2 \pi n$$
$$x = 2 \pi n + \frac{\pi}{3}$$
