Question

diffrentiate y = sin x/ x3​

Answer 1

Answer:

$y = \frac{sin \: x}{ {x}^{3} } \\ \frac{dy}{dx} = \frac{ {x}^{3} \times cos \: x - sin \: x \times 3 {x}^{2} }{ {x}^{6} } \\ = \frac{ x cos \: x - 3sin \: x \times }{ {x}^{4} } \\ = \frac{cos \: x}{ {x}^{3} } - \frac{3sin \: x}{ {x}^{4} } \\ \\ \red{\mathfrak{\underline{\large{Hope \: It \: Helps \: You }}}} \\ \green{\mathfrak{\underline{\large{Mark \: Me \: Brainliest}}}}$
