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![ The best thing about life is you don't know what to expect #2 20131024 15:31:10
Re: Derivative of arcsec(1/t)Hi infinitebrain; 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.
