$$\frac{\sin{\left(\frac{35 x}{2} \right)}}{\frac{35}{2} x} = 0$$
Solución detallada
Tenemos la ecuación
$$\frac{\sin{\left(\frac{35 x}{2} \right)}}{\frac{35}{2} x} = 0$$
cambiamos
$$\frac{- x + \frac{2 \sin{\left(\frac{35 x}{2} \right)}}{35}}{x} = 0$$
$$-1 + \frac{\sin{\left(\frac{35 x}{2} \right)}}{\frac{35}{2} x} = 0$$
Sustituimos
$$w = \sin{\left(\frac{35 x}{2} \right)}$$
Tenemos la ecuación:
$$-1 + \frac{\sin{\left(\frac{35 x}{2} \right)}}{\frac{35}{2} x} = 0$$
Usamos la regla de proporciones:
De a1/b1 = a2/b2 se deduce a1*b2 = a2*b1,
En nuestro caso
a1 = 2*sin(35*x/2)/35

b1 = x

a2 = 1

b2 = 1

signo obtendremos la ecuación
$$\frac{2 \sin{\left(\frac{35 x}{2} \right)}}{35} = x$$
$$\frac{2 \sin{\left(\frac{35 x}{2} \right)}}{35} = x$$
Abrimos los paréntesis en el miembro izquierdo de la ecuación
2*sin35*x/2/35 = x

Esta ecuación no tiene soluciones
hacemos cambio inverso
$$\sin{\left(\frac{35 x}{2} \right)} = w$$
Tenemos la ecuación
$$\sin{\left(\frac{35 x}{2} \right)} = w$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$\frac{35 x}{2} = 2 \pi n + \operatorname{asin}{\left(w \right)}$$
$$\frac{35 x}{2} = 2 \pi n - \operatorname{asin}{\left(w \right)} + \pi$$
O
$$\frac{35 x}{2} = 2 \pi n + \operatorname{asin}{\left(w \right)}$$
$$\frac{35 x}{2} = 2 \pi n - \operatorname{asin}{\left(w \right)} + \pi$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$\frac{35}{2}$$
sustituimos w:
