___ / pi\ \/ 2 sin|x + --| = ----- \ 3 / 2
$$\sin{\left(x + \frac{\pi}{3} \right)} = \frac{\sqrt{2}}{2}$$
Detail solution
Given the equation
$$\sin{\left(x + \frac{\pi}{3} \right)} = \frac{\sqrt{2}}{2}$$
- this is the simplest trigonometric equation
This equation is transformed to
$$x + \frac{\pi}{3} = 2 \pi n + \operatorname{asin}{\left(\frac{\sqrt{2}}{2} \right)}$$
$$x + \frac{\pi}{3} = 2 \pi n - \operatorname{asin}{\left(\frac{\sqrt{2}}{2} \right)} + \pi$$
Or
$$x + \frac{\pi}{3} = 2 \pi n + \frac{\pi}{4}$$
$$x + \frac{\pi}{3} = 2 \pi n + \frac{3 \pi}{4}$$
, where n - is a integer
Move
$$\frac{\pi}{3}$$
to right part of the equation
with the opposite sign, in total:
$$x = 2 \pi n - \frac{\pi}{12}$$
$$x = 2 \pi n + \frac{5 \pi}{12}$$
$$\sin{\left(x + \frac{\pi}{3} \right)} = \frac{\sqrt{2}}{2}$$
- this is the simplest trigonometric equation
This equation is transformed to
$$x + \frac{\pi}{3} = 2 \pi n + \operatorname{asin}{\left(\frac{\sqrt{2}}{2} \right)}$$
$$x + \frac{\pi}{3} = 2 \pi n - \operatorname{asin}{\left(\frac{\sqrt{2}}{2} \right)} + \pi$$
Or
$$x + \frac{\pi}{3} = 2 \pi n + \frac{\pi}{4}$$
$$x + \frac{\pi}{3} = 2 \pi n + \frac{3 \pi}{4}$$
, where n - is a integer
Move
$$\frac{\pi}{3}$$
to right part of the equation
