Question 956099
Find all angles that satisfy csc^-1 undefined in degrees
--------------------------
The csc of some angles is undefined.
csc^-1 , if you mean the arccsc or invcsc, is not.  An angle can be found for any given csc.
---
If you mean 1/csc, that's the sine.  It's defined for all angles.
========================================================
------------
csc = 1/sin
--> all angles with sine of zero (0).
