If f(t)= √((t^2-1)/(t^2-1))
Find f '(t)
I have tried it several times using f(x+h)-f(x) / h, but I always get lost and don't know how to solve it.
Could someone help me?
Thank you
Why dont you just use the rules of differntiation?
I dont see why you would try to find the derivative of f using the limit definition of the derivative.
Two obvious approaches that stand out.
first you could use the chain rule followed by the quotient rule for differentiation.
or simplify
then use the quotient rule and chain rule.
I find after some quick and sloppy calculations (so forgive me if this is not completely accurate)
