Solución
Solución detallada
Tenemos la ecuación
$$\pi \sin{\left(\pi x \right)} = 1$$
es la ecuación trigonométrica más simple
La ecuación se convierte en
$$\sin{\left(\pi x \right)} = \frac{1}{\pi}$$
Esta ecuación se reorganiza en
$$\pi x = 2 \pi n + \operatorname{asin}{\left(\frac{1}{\pi} \right)}$$
$$\pi x = 2 \pi n - \operatorname{asin}{\left(\frac{1}{\pi} \right)} + \pi$$
O
$$\pi x = 2 \pi n + \operatorname{asin}{\left(\frac{1}{\pi} \right)}$$
$$\pi x = 2 \pi n - \operatorname{asin}{\left(\frac{1}{\pi} \right)} + \pi$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$\pi$$
obtenemos la respuesta:
$$x_{1} = \frac{2 \pi n + \operatorname{asin}{\left(\frac{1}{\pi} \right)}}{\pi}$$
$$x_{2} = \frac{2 \pi n - \operatorname{asin}{\left(\frac{1}{\pi} \right)} + \pi}{\pi}$$
$$\pi \sin{\left(\pi x \right)} = 1$$
es la ecuación trigonométrica más simple
Dividamos ambos miembros de la ecuación en pi
La ecuación se convierte en
$$\sin{\left(\pi x \right)} = \frac{1}{\pi}$$
Esta ecuación se reorganiza en
$$\pi x = 2 \pi n + \operatorname{asin}{\left(\frac{1}{\pi} \right)}$$
$$\pi x = 2 \pi n - \operatorname{asin}{\left(\frac{1}{\pi} \right)} + \pi$$
O
$$\pi x = 2 \pi n + \operatorname{asin}{\left(\frac{1}{\pi} \right)}$$
$$\pi x = 2 \pi n - \operatorname{asin}{\left(\frac{1}{\pi} \right)} + \pi$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$\pi$$
obtenemos la respuesta:
$$x_{1} = \frac{2 \pi n + \operatorname{asin}{\left(\frac{1}{\pi} \right)}}{\pi}$$
$$x_{2} = \frac{2 \pi n - \operatorname{asin}{\left(\frac{1}{\pi} \right)} + \pi}{\pi}$$
