$lim_{x \to 1} \sin (π x)$

Step 1

Evaluate the limit.

Step 1.1

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

$\sin (lim_{x \to 1} π x)$

Step 1.2

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

$\sin (π lim_{x \to 1} x)$

Step 2

Evaluate the limit of $x$ by plugging in $1$ for $x$ .

$\sin (π \cdot 1)$

Step 3

Simplify the answer.

Step 3.1

Multiply $π$ by $1$ .

$\sin (π)$

Step 3.2

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant.

$\sin (0)$

Step 3.3

The exact value of $\sin (0)$ is $0$ .

$0$
