limit as x approaches 0 of (4tan(x))/x

解

x \to 0 lim (\frac{4 tan ( x )}{x})

解

4

解答ステップ

x \to 0 lim (\frac{4 tan ( x )}{x})

x \to a lim [c \cdot f (x)] = c \cdot x \to a lim f (x)

= 4 \cdot x \to 0 lim (\frac{tan ( x )}{x})

ロピタルの定理を適用する

= 4 \cdot x \to 0 lim (\frac{sec ^{2} ( x )}{1})

値を挿入する

x = 0

= 4 \cdot \frac{sec ^{2} ( 0 )}{1}

簡素化

4 \cdot \frac{sec ^{2} ( 0 )}{1} : 4

= 4
