I can't for the life of me remember how to do these :(
lim t->0 of (t^(3))/[tan(2t)]^(3)
lim t->0 of [sqrt(1+tan(t)) - sqrt(1+sin(t))]/(t^(3))
These 2 also =(
evaluate dy if y=x^(3) - 2x^(2) + 1 if x=2 and dx= 0.2 I don't see why you would need dx? Wouldn't you just differentiate x and then plug in the 2? hmm...
And this last one
approximate sqrt(64.05) using differentials.
THANKS IN ADVANCE!!!!:)
