$lim_{x \to π} \sin (x)$

Step 1

Change the two-sided limit into a left sided limit.

$lim_{x \to π^{-}} \sin (x)$

Step 2

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

$\sin (lim_{x \to π^{-}} x)$

Step 3

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

$\sin (π)$

Step 4

Simplify the answer.
