$cot0$ : 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 $0$ :

$sec0=1/cos0=1/1=1$
