The solution
Detail solution
Given the equation
$$\sin{\left(\pi x \right)} = 1$$
- this is the simplest trigonometric equation
This equation is transformed to
$$\pi x = 2 \pi n + \operatorname{asin}{\left(1 \right)}$$
$$\pi x = 2 \pi n - \operatorname{asin}{\left(1 \right)} + \pi$$
Or
$$\pi x = 2 \pi n + \frac{\pi}{2}$$
$$\pi x = 2 \pi n + \frac{\pi}{2}$$
, where n - is a integer
Divide both parts of the equation by
$$\pi$$
we get the answer:
$$x_{1} = \frac{2 \pi n + \frac{\pi}{2}}{\pi}$$
$$x_{2} = \frac{2 \pi n + \frac{\pi}{2}}{\pi}$$
$$\sin{\left(\pi x \right)} = 1$$
- this is the simplest trigonometric equation
This equation is transformed to
$$\pi x = 2 \pi n + \operatorname{asin}{\left(1 \right)}$$
$$\pi x = 2 \pi n - \operatorname{asin}{\left(1 \right)} + \pi$$
Or
$$\pi x = 2 \pi n + \frac{\pi}{2}$$
$$\pi x = 2 \pi n + \frac{\pi}{2}$$
, where n - is a integer
Divide both parts of the equation by
$$\pi$$
we get the answer:
$$x_{1} = \frac{2 \pi n + \frac{\pi}{2}}{\pi}$$
$$x_{2} = \frac{2 \pi n + \frac{\pi}{2}}{\pi}$$
