A simpler method is to apply L'Hopitals rule if you get a 0 0 indeterminate form when evaluating your expression at the limit. lim_ (xrarroo) (sqrt (x^2+x)-x)=1/2 The initial form for the limit is indeterminate oo-oo So, use the conjugate. = −1 ε + ε ε. Step 3: Apply the limit value by substituting x = 2 in the equation to find the limit. Since, f (3) = |3 − 3| = 0, we have, f (x) − f (3) x − 3 = |x −3| x −3. lim_ (x->oo) x^3e^ (-x^2) = 0 Write the limit as: lim_ (x->oo) x^3e^ (-x^2) = lim_ (x->oo) x^3/e^ (x^2) It is now in the indefinite form oo/oo and we can apply l'Hospital's rule
