All rights reserved. things. unimaginable amount. What is the most effective way for float and double comparison? Are $\log_1 1$ and $\log_0 0$ indeterminate forms? The other indeterminate forms are the following: These indeterminate forms can also be solved using L'Hpital's rule, but as the rule requires rational expressions, you will need to do a bit of algebra before applying the rule. Moreover, $\lim_{x\to0^+}f(x)/g(x)=3$ when $f(x)=1+3/x$ and $g(x)=2+1/x$ even though $\lim_{x\to0^+}f(x)=\infty$ and $\lim_{x\to0^+}g(x)=\infty$. \end{align} \]. Den hr e-postadressen skyddas mot spambots. Surprisingly enough, you can have different answers depending on how this division is approached. The cosine of \(0\) is \(1,\) so both the numerator and the denominator approach \(0\) as \(x \to 0.\) This suggests the use of L'Hpital's rule, that is: \[ \lim_{x \to 0^+} \left( \frac{\cos{x}}{x}-\frac{1}{x}\right) = \lim_{x \to 0^+}\frac{\sin{x}}{1}\].
