Step 1.1

Move the term $8$ outside of the limit because it is constant with respect to $x$ .

$8 lim_{x \to 8} \cos (x)$

Step 1.2

Move the limit inside the trig function because cosine is continuous.

$8 \cos (lim_{x \to 8} x)$

Step 2

Evaluate the limit of $x$ by plugging in $8$ for $x$ .

$8 \cos (8)$
