Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$y e^{- x} = x - 1$$
Коэффициент при y равен
$$e^{- x}$$
entonces son posibles los casos para x :
Consideremos todos los casos con detalles:
/ re(x) re(x) \ re(x) re(x)
y1 = I*\(-1 + re(x))*e *sin(im(x)) + cos(im(x))*e *im(x)/ + (-1 + re(x))*cos(im(x))*e - e *im(x)*sin(im(x))
$$y_{1} = i \left(\left(\operatorname{re}{\left(x\right)} - 1\right) e^{\operatorname{re}{\left(x\right)}} \sin{\left(\operatorname{im}{\left(x\right)} \right)} + e^{\operatorname{re}{\left(x\right)}} \cos{\left(\operatorname{im}{\left(x\right)} \right)} \operatorname{im}{\left(x\right)}\right) + \left(\operatorname{re}{\left(x\right)} - 1\right) e^{\operatorname{re}{\left(x\right)}} \cos{\left(\operatorname{im}{\left(x\right)} \right)} - e^{\operatorname{re}{\left(x\right)}} \sin{\left(\operatorname{im}{\left(x\right)} \right)} \operatorname{im}{\left(x\right)}$$
y1 = i*((re(x) - 1)*exp(re(x))*sin(im(x)) + exp(re(x))*cos(im(x))*im(x)) + (re(x) - 1)*exp(re(x))*cos(im(x)) - exp(re(x))*sin(im(x))*im(x)
