Question #91dad

1 Answer

Jul 28, 2016

Not sure what the question is but
if it is to identify the "excluded values"
then #x !in {k*pi|kinZZ}#

Explanation:

Since the function definition requires division by #sin x#
then #sin x != 0#
#rarr x != k* pi# for any #kinZZ#

Note that if #k# is an odd integer
the function evaluates as a removable discontinuity.
