Answer
$1.0025$
Work Step by Step
Step 1: Ensure that the calculator is in radian.
Step 2: $\csc \frac{3}{2}=\frac{1}{\sin \frac{3}{2}}$
Step 3: Type $\frac{1}{\sin \frac{3}{2}}$ into the calculator and press enter.
Step 4: Rounding out the answer to 4 decimal places,
$\frac{1}{\sin \frac{3}{2}}\approx1.0025$.
