Answer
$1$
Work Step by Step
RECALL:
(1) $\csc{\theta}=\frac{1}{\sin{\theta}}$
(2) $\cot{\theta} = \frac{\cos{\theta}}{\sin{\theta}}$
With $\sin{\frac{\pi}{2}}=1$ and $\cos{\frac{\pi}{2}}=0$, then
$\csc\dfrac {\pi }{2}+\cot \dfrac {\pi }{2}
\\=\dfrac {1}{\sin \dfrac {\pi }{2}}+\dfrac {\cos \dfrac {\pi }{2}}{\sin \dfrac {\pi }{2}}
\\=\dfrac {1}{1}+\dfrac {0}{1}
\\=1+0
\\=1$
