Disclaimer: on the attachment bellow is a long ass rant on my experience with Hyperbolic functions on my Calculus class.

Both solutions work.
1/(y-sqrt(y^2 - 1)) = y + sqrt(y^2 - 1)
Good effort, I guess. It amazes me that people can put in the time and effort to make a pdf but not actually learn what they are talking about.
I guess picking up a tool and making something shitty passes for "productivity" in your mind.

thanks for being the only response to my pathetic thread although I see that you didn't read the pdf (which is just a page and a half)

sinh is defined for negative numbers. Don't you violate your own objection by adding sinh?
Math is full of paradoxes. If you try and eliminate them all, you will end up with nothing. However, interesting derivation.
It is just that, in learning trig, it is always best to use the identity to turn the functions into e^x, simply because remembering all the little trig tricks is impossible. By converting everything into e^x, it is easy to convert to other functions, whereas trying to remember trig tricks is nearly impossible if you don't use them everyday.
8/10 for getting me to reply.
