Solución
Ha introducido
[src]
f(t) = 2*(1 - cos(t))*2*(t - sin(t))
$$f{\left(t \right)} = 2 \cdot 2 \left(1 - \cos{\left(t \right)}\right) \left(t - \sin{\left(t \right)}\right)$$
f = (2*(2*(1 - cos(t))))*(t - sin(t))

Extremos de la función
Para hallar los extremos hay que resolver la ecuación
$$\frac{d}{d t} f{\left(t \right)} = 0$$
(la derivada es igual a cero),
y las raíces de esta ecuación serán los extremos de esta función:
$$\frac{d}{d t} f{\left(t \right)} = $$
primera derivada
$$4 \left(1 - \cos{\left(t \right)}\right)^{2} + 4 \left(t - \sin{\left(t \right)}\right) \sin{\left(t \right)} = 0$$

ecuación de la asíntota inclinada a la derecha:
$$y = \left\langle 0, 8\right\rangle t$$
$$\lim_{t \to -\infty}\left(\frac{4 \left(1 - \cos{\left(t \right)}\right) \left(t - \sin{\left(t \right)}\right)}{t}\right) = \left\langle 0, 8\right\rangle$$
Tomamos como el límite
es decir,
ecuación de la asíntota inclinada a la izquierda:
$$y = \left\langle 0, 8\right\rangle t$$
$$\lim_{t \to \infty}\left(\frac{4 \left(1 - \cos{\left(t \right)}\right) \left(t - \sin{\left(t \right)}\right)}{t}\right) = \left\langle 0, 8\right\rangle$$

Paridad e imparidad de la función
Comprobemos si la función es par o impar mediante las relaciones f = f(-t) и f = -f(-t).
Pues, comprobamos:
$$2 \cdot 2 \left(1 - \cos{\left(t \right)}\right) \left(t - \sin{\left(t \right)}\right) = 4 \left(1 - \cos{\left(t \right)}\right) \left(- t + \sin{\left(t \right)}\right)$$
- No
$$2 \cdot 2 \left(1 - \cos{\left(t \right)}\right) \left(t - \sin{\left(t \right)}\right) = - 4 \left(1 - \cos{\left(t \right)}\right) \left(- t + \sin{\left(t \right)}\right)$$
- No
es decir, función
no es
par ni impar
