#cot0#: undefined
#csc0#: undefined
#sec0=1#

#0# is a special angle. #cot#, #csc#, and #sec# are actually just the reciprocals of #tan#, #sin#, and #cos# respectively.

Solving cot #0#:

#cot0=1/tan0=1/0" this is undefined"#

Solving csc #0#:

#csc0=1/sin0=1/0" this is undefined"#

Solving sec #0#:

#sec0=1/cos0=1/1=1#
