$f (2) = \frac{\cos (\frac{π}{x})}{x - 2}$

Step 1

Replace the variable $x$ with $2$ in the expression.

$f (2) = \frac{\cos (\frac{π}{2})}{(2) - 2}$

Step 2

Subtract $2$ from $2$ .

$f (2) = \frac{\cos (\frac{π}{2})}{0}$

Step 3

The expression contains a division by $0$ . The expression is undefined.
