 lim (a*cos(t))
t->oo          
$$\lim_{t \to \infty}\left(a \cos{\left(t \right)}\right)$$
Limit(a*cos(t), t, oo, dir='-')
Lopital's rule
There is no sense to apply Lopital's rule to this function since there is no indeterminateness of 0/0 or oo/oo type

<-1, 1>*a
$$\left\langle -1, 1\right\rangle a$$
Other limits t→0, -oo, +oo, 1
$$\lim_{t \to \infty}\left(a \cos{\left(t \right)}\right) = \left\langle -1, 1\right\rangle a$$
$$\lim_{t \to 0^-}\left(a \cos{\left(t \right)}\right) = a$$
More at t→0 from the left
$$\lim_{t \to 0^+}\left(a \cos{\left(t \right)}\right) = a$$
More at t→0 from the right
$$\lim_{t \to 1^-}\left(a \cos{\left(t \right)}\right) = a \cos{\left(1 \right)}$$
More at t→1 from the left
$$\lim_{t \to 1^+}\left(a \cos{\left(t \right)}\right) = a \cos{\left(1 \right)}$$
More at t→1 from the right
$$\lim_{t \to -\infty}\left(a \cos{\left(t \right)}\right) = \left\langle -1, 1\right\rangle a$$
More at t→-oo
