: if i want to find y' of y=tan(arcsec x)
: should i put it into algebraic form or just use the chain rule OR does it even matter...?
************************************
It really does not matter.
This one converts to nice algebraic form [y = sqrt(x^2-1)]. However, most of these do not convert so easily. Then you have to use the chain rule.
As you can see, the algebraic form requires use of chain rule too.
