Puntos de cruce con el eje de coordenadas Y
El gráfico cruce el eje Y cuando x es igual a 0:
sustituimos x = 0 en x*cot(5*x).
0cot(05)0 \cot{\left(0 \cdot 5 \right)}
Resultado:
f(0)=NaNf{\left(0 \right)} = \text{NaN}
- no hay soluciones de la ecuación
Extremos de la función
Para hallar los extremos hay que resolver la ecuación
ddxf(x)=0\frac{d}{d x} f{\left(x \right)} = 0
(la derivada es igual a cero),
y las raíces de esta ecuación serán los extremos de esta función:
ddxf(x)=\frac{d}{d x} f{\left(x \right)} =
primera derivada
x(5cot2(5x)5)+cot(5x)=0x \left(- 5 \cot^{2}{\left(5 x \right)} - 5\right) + \cot{\left(5 x \right)} = 0

Puntos de flexiones
Hallemos los puntos de flexiones, para eso hay que resolver la ecuación
d2dx2f(x)=0\frac{d^{2}}{d x^{2}} f{\left(x \right)} = 0
(la segunda derivada es igual a cero),
las raíces de la ecuación obtenida serán los puntos de flexión para el gráfico de la función indicado:

[1.54505036738754,2.18082433188578]\left[-1.54505036738754, 2.18082433188578\right]
Convexa en los intervalos
(,99.5880854648633]\left(-\infty, -99.5880854648633\right]
Asíntotas horizontales
Hallemos las asíntotas horizontales mediante los límites de esta función con x->+oo y x->-oo
True

Tomamos como el límite
es decir,
ecuación de la asíntota horizontal a la izquierda:
y=limx(xcot(5x))y = \lim_{x \to -\infty}\left(x \cot{\left(5 x \right)}\right)
True

Tomamos como el límite
es decir,
ecuación de la asíntota horizontal a la derecha:
y=limx(xcot(5x))y = \lim_{x \to \infty}\left(x \cot{\left(5 x \right)}\right)
Asíntotas inclinadas
Se puede hallar la asíntota inclinada calculando el límite de la función x*cot(5*x), dividida por x con x->+oo y x ->-oo
limxcot(5x)=cot()\lim_{x \to -\infty} \cot{\left(5 x \right)} = - \cot{\left(\infty \right)}
Tomamos como el límite
es decir,
ecuación de la asíntota inclinada a la izquierda:
y=xcot()y = - x \cot{\left(\infty \right)}
limxcot(5x)=cot()\lim_{x \to \infty} \cot{\left(5 x \right)} = \cot{\left(\infty \right)}
Tomamos como el límite
es decir,
ecuación de la asíntota inclinada a la derecha:
y=xcot()y = x \cot{\left(\infty \right)}
Paridad e imparidad de la función
Comprobemos si la función es par o impar mediante las relaciones f = f(-x) и f = -f(-x).
Pues, comprobamos:
xcot(5x)=xcot(5x)x \cot{\left(5 x \right)} = x \cot{\left(5 x \right)}
- Sí
xcot(5x)=xcot(5x)x \cot{\left(5 x \right)} = - x \cot{\left(5 x \right)}
- No
es decir, función
es
par
