$lim_{x \to \frac{π}{2}} \csc (x)$

Step 1

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

$\csc (lim_{x \to \frac{π}{2}} x)$

Step 2

Evaluate the limit of $x$ by plugging in $\frac{π}{2}$ for $x$ .

$\csc (\frac{π}{2})$

Step 3

The exact value of $\csc (\frac{π}{2})$ is $1$ .
