Derivative of arcsec(1/t)

My textbook keeps saying it is

. Could someone work it step by step and show me how that answer is derived. I would appreciate it because I keep getting lost. Thanks![

Re: Derivative of arcsec(1/t)

Hi infinitebrain;

Your textbook is correct.

You can start with this page which shows how to get the derivative of arcsec

Then you just use the chain rule.

From the above link:

The chain rule says:

Now just substitute u = 1 / t and clean up.

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
