Best ResponseYou've already chosen the best response.2why is your limit has x approahing 1 and the function is in terms of t?

Best ResponseYou've already chosen the best response.0that was a typo an my behalf :$

Best ResponseYou've already chosen the best response.2factor the numerator to (1+t)(1t) then cancel the (1+t) out so you are left with \[\sqrt{1t}\]

Best ResponseYou've already chosen the best response.0@kphilips2010 that method is not correct

Best ResponseYou've already chosen the best response.2why is that wrong?

Best ResponseYou've already chosen the best response.0because it's not a binomia

Best ResponseYou've already chosen the best response.2they are not conjugates, they are addition and addition is commutative

Best ResponseYou've already chosen the best response.2I didnt say it was a binomial, I am saying you can factor the binomial into (1+t)(1t)

Best ResponseYou've already chosen the best response.0but isnt there another method, like multiply by the denominator or something of the like

Best ResponseYou've already chosen the best response.0so do i keep the square root sign ?

Best ResponseYou've already chosen the best response.0If you want to be rigorous about it, you need to state that for limits, you are looking at values of t close to 1, but NOT EQUAL to 1. if t is not equal to 1, then:\[\frac{1t^2}{1+t}=\frac{(1t)(1+t)}{(1+t)}=1t\]We can only divide those monomials out if t DOESNT equal 1, which is ok in limits, we dont want t to equal 1. Im making an emphasis on the fact that if t was equal to 1, then that division doesnt make any sense.
