Temukan $$$\frac{d}{dx} \left(e^{x^{3}}\right)$$$.
Solusi
Fungsi $$$e^{x^{3}}$$$ merupakan komposisi $$$f{\left(g{\left(x \right)} \right)}$$$ dari dua fungsi $$$f{\left(u \right)} = e^{u}$$$ dan $$$g{\left(x \right)} = x^{3}$$$.
Terapkan aturan rantai $$$\frac{d}{dx} \left(f{\left(g{\left(x \right)} \right)}\right) = \frac{d}{du} \left(f{\left(u \right)}\right) \frac{d}{dx} \left(g{\left(x \right)}\right)$$$:
$${\color{red}\left(\frac{d}{dx} \left(e^{x^{3}}\right)\right)} = {\color{red}\left(\frac{d}{du} \left(e^{u}\right) \frac{d}{dx} \left(x^{3}\right)\right)}$$Turunan dari fungsi eksponensial adalah $$$\frac{d}{du} \left(e^{u}\right) = e^{u}$$$:
$${\color{red}\left(\frac{d}{du} \left(e^{u}\right)\right)} \frac{d}{dx} \left(x^{3}\right) = {\color{red}\left(e^{u}\right)} \frac{d}{dx} \left(x^{3}\right)$$Kembalikan ke variabel semula:
$$e^{{\color{red}\left(u\right)}} \frac{d}{dx} \left(x^{3}\right) = e^{{\color{red}\left(x^{3}\right)}} \frac{d}{dx} \left(x^{3}\right)$$Terapkan aturan pangkat $$$\frac{d}{dx} \left(x^{n}\right) = n x^{n - 1}$$$ dengan $$$n = 3$$$:
$$e^{x^{3}} {\color{red}\left(\frac{d}{dx} \left(x^{3}\right)\right)} = e^{x^{3}} {\color{red}\left(3 x^{2}\right)}$$Dengan demikian, $$$\frac{d}{dx} \left(e^{x^{3}}\right) = 3 x^{2} e^{x^{3}}$$$.
Jawaban
$$$\frac{d}{dx} \left(e^{x^{3}}\right) = 3 x^{2} e^{x^{3}}$$$A
