Find the derivative. Simplify where possible.
$ g(x) = \sinh^2 x $
2 $\sinh x \cosh x$
we know the derivative of signed H of X is co sign a cheque. Rex, Therefore, if are you is sign a true pax thingy of you Is you squared? We can write this as two year times co signed h of axe is equivalent to two co signed h of axe times signed H A box because now repugnant. If this is air you over here, we're plugging in. Are you with this? Therefore we can simplify this to be g prime of axe is signed Age of two X Now remember, this is a special case trick identity list in the textbook.
