To find the limit of the given expression as
approaches
, we can use the fact that \(\sin(2x+16)\) approaches 0 as
approaches
. We can rewrite the expression as:
As
approaches
, the numerator
approaches 0, and the denominator \(\sin(2x+16)\) approaches 0. This is an indeterminate form of type
, so we can apply L'Hôpital's Rule.Taking the derivative of the numerator and denominator with respect to
, we get:
Now, as
approaches
, the denominator \(\cos(2x+16)\) approaches \(\cos(0)\), which is 1. Therefore, the limit is:
So, the correct answer is
.
