In Exercises 135 and 136, verify each identity.

(a) $\operatorname{arccsc} x=\arcsin \frac{1}{x},|x| \geq 1$

(b) $\arctan x+\arctan \frac{1}{x}=\frac{\pi}{2}, x>0$

Equation Transcription:

$arccsc\ x\ =\ arcsin\ \frac{1}{x},\ |x|\ \geq{}\ 1$

$arctan\ x\ +\ arctan\ \frac{1}{x}=\frac{\pi{}}{2},\ x\ >\ 0$

Text Transcription:

arccsc x = arcsin 1/x, |x| geq 1

arctan x + arctan 1/x=pi/2, x > 0
