Impara online a risolvere i problemi di passo dopo passo. (x)->(-infinito)lim((3x)/((x^2+1)^(1/2))). Applicare la formula: \lim_{x\to c}\left(\frac{a}{b}\right)=\lim_{x\to c}\left(\frac{\frac{a}{sign\left(c\right)fgrow\left(b\right)}}{\frac{b}{sign\left(c\right)fgrow\left(b\right)}}\right), dove a=3x, b=\sqrt{x^2+1}, c=- \infty , a/b=\frac{3x}{\sqrt{x^2+1}} e x->c=x\to{- \infty }. Applicare la formula: \lim_{x\to c}\left(\frac{a}{b}\right)=\lim_{x\to c}\left(\frac{radicalfrac\left(a\right)}{radicalfrac\left(b\right)}\right), dove a=\frac{3x}{-x}, b=\frac{\sqrt{x^2+1}}{-x} e c=- \infty . Applicare la formula: \lim_{x\to c}\left(\frac{a}{b}\right)=\lim_{x\to c}\left(\frac{splitfrac\left(a\right)}{splitfrac\left(b\right)}\right), dove a=\frac{3x}{-x}, b=\sqrt{\frac{x^2+1}{\left(-x\right)^{2}}} e c=- \infty . Applicare la formula: \frac{a}{a}=1, dove a=x e a/a=\frac{3x}{-x}.
