Ecuación diferencial y"'+y'=tanx
El profesor se sorprenderá mucho al ver tu solución correcta😉
Solución
/ log(-1 + sin(x)) log(1 + sin(x))\
y(x) = C1 - log(cos(x)) + C3*cos(x) + |C2 + ---------------- - ---------------|*sin(x)

$$y{\left(x \right)} = C_{1} + C_{3} \cos{\left(x \right)} + \left(C_{2} + \frac{\log{\left(\sin{\left(x \right)} - 1 \right)}}{2} - \frac{\log{\left(\sin{\left(x \right)} + 1 \right)}}{2}\right) \sin{\left(x \right)} - \log{\left(\cos{\left(x \right)} \right)}$$
