2.1.66 Calculation of Limits
Condition: find \ (d y / d x \) and \ (d^{2} y / d x^{2} \) for the specified functions: a) \ (y = \ frac {x} {^{2} -1 \ risht) \), b) \ (x = \ cos \ left (\ frac {t} {2} \ right), y = t- \ sin t \)
Calculation of Various Limits, Using L'Hopital's Rule, Remarkable Limits, Power Series, Equivalent Values of Various Other Methods.
