FOR FURTHER INFORMATION For a geometric approach to this exercise,see the article “A Geometric Proof of \(\lim _{d \rightarrow 0^{+}}(-d \ln d)=0\)” by John H. Mathews in The College Mathematics Journal.To view this article,go to MathArticles.com.

Proof Prove that if \(f(x) \geq 0\), \(\lim _{x \rightarrow a} f(x)=0\), and \(\lim _{x \rightarrow a} g(x)=\infinity\), then \(\lim _{x \rightarrow a} f(x)^{g(x)}=0\)

 

Text Transcription:

lim_d rightarrow 0^+ (-d \ln d)=0

f(x) geq 0

lim_x rightarrow f(x)=0

lim_x rightarrow f(x)=infinity

lim_x rightarrow f(x)^g(x) = 0
