Solución
Solución detallada
ErfRule(a=-9/20, b=699/25, c=-8753/20, context=exp(-9*x**2/20 + 699*x/25 - 8753/20), symbol=x)
Ahora simplificar:
5 π erf ( 5 ( 15 x − 466 ) 50 ) 3 e 1669 500 \frac{\sqrt{5} \sqrt{\pi} \operatorname{erf}{\left(\frac{\sqrt{5} \left(15 x - 466\right)}{50} \right)}}{3 e^{\frac{1669}{500}}} 3 e 500 1669 5 π erf ( 50 5 ( 15 x − 466 ) )
Añadimos la constante de integración:
5 π erf ( 5 ( 15 x − 466 ) 50 ) 3 e 1669 500 + c o n s t a n t \frac{\sqrt{5} \sqrt{\pi} \operatorname{erf}{\left(\frac{\sqrt{5} \left(15 x - 466\right)}{50} \right)}}{3 e^{\frac{1669}{500}}}+ \mathrm{constant} 3 e 500 1669 5 π erf ( 50 5 ( 15 x − 466 ) ) + constant
Respuesta:
