<p>Here is a trick we were taught today in math:
Make a chart of
Sec Tan Sec
Then put the corresponding cofunctions with a negative sign in front
-Csc Cot Csc
Then to find the derivative of one of the above, you cover up the one you are looking for and read what remains of the line to find the derivative.
For example, to find the derivative of Tan, cover it up.
You are left with Sec Sec or Sec^2X or
For example, to find the derivative of CSC, Cover it up.
You are left with -CotCsc or -CscCot.
I think this is very easy to remember. The chart once again.</p>

<p>Sec Tan Sec
-Csc Cot Csc</p>

<p>Easy enough and actually useful.</p>
