Question

Differentiation Of Y = Sin ( x² + 2x + 5 )​

Answer 1

Q. Differentiation of Y = Sin (x² + 5)

$\mathfrak{\huge{\red{\underline{\underline{AnswEr :}}}}}$

⚘ Let f(x) = sin(x² + 5)

⚘ y = sin(x² + 5)

we need to derivative y , w. r. t. x

$\huge{ \frac{dy}{dx} = \frac{d(sin( {x}^{2} + 5)) }{dx} }$

⇒ cos (x² + 5) × $\frac{d( {x}^{2} + 5) }{dx}$

$\boxed{sin \: x' = \cos \: x }$

⇒ cos (x² + 5) × $\frac{d( {x}^{2} )}{dx} + \frac{d(5)}{dx}$

⇒ cos (x² + 5) × ${2x}^{(2 - 1)} + 0$

⇒ cos (x² + 5) × 2x

⇒2x cos (x² + 5)
