Solución detallada
Tenemos una ecuación lineal:
w*pi*p = 2*cos((2*(157/50))/4)*sqrt((2*10)/(2*6*(83/10)*(10)^(-3)))*30/(157/50)
Abrimos los paréntesis en el miembro derecho de la ecuación
w*pi*p = 2*cos2*+157/50)/4)*sqrt2*102*6*+83/1010^-3))*30/157/50
Dividamos ambos miembros de la ecuación en pi*p
w = 270.773981496084*cos(157/100) / (pi*p)
Obtenemos la respuesta: w = 0.0686354272539299/p
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$\pi p w = \frac{30 \sqrt{\frac{20}{0.001 \frac{12 \cdot 83}{10}}} \cdot 2 \cos{\left(\frac{2 \frac{157}{50}}{4} \right)}}{\frac{157}{50}}$$
Коэффициент при w равен
$$\pi p$$
entonces son posibles los casos para p :
$$p < 0$$
$$p = 0$$
Consideremos todos los casos con detalles:
Con
$$p < 0$$
la ecuación será
$$- \pi w - \frac{30 \sqrt{\frac{20}{0.001 \frac{12 \cdot 83}{10}}} \cdot 2 \cos{\left(\frac{2 \frac{157}{50}}{4} \right)}}{\frac{157}{50}} = 0$$
su solución
$$w = -0.0686354272539299$$
Con
$$p = 0$$
la ecuación será
$$- \frac{30 \sqrt{\frac{20}{0.001 \frac{12 \cdot 83}{10}}} \cdot 2 \cos{\left(\frac{2 \frac{157}{50}}{4} \right)}}{\frac{157}{50}} = 0$$
