Solution to Example 7: The range of the cosine function is. -1 <= cos x <= 1. Divide all terms of the above inequality by x, for x positive. -1 / x <= cos x / x <= 1 / x. Now as x takes larger values without bound (+infinity) both -1 / x and 1 / x approaches 0. Hence by the squeezing theorem the above limit is given by.

WebJust to provide a contrasting example we try to calculate $$\lim_{h \to 0}\frac{h}{\sqrt{5h + 1} - 1}$$ If we follow as before we will see that limit of both numerator and denominator is $0$ and hence rule 3) can't be applied precisely because the denominator limit is $0$.

WebWe can solve this limit by applying L'Hôpital's rule, which consists of calculating the derivative of both the numerator and the denominator separately.
