Question

find the derivative of (2x square +3 )sin x​

Answer 1

Answer:

$\bf{let \: y = (2 {x}^{2} + 3)sin \: x} \\ \\ \bf{differentiating \: on \: both \: sides \: by \: chain \: rule} \\ \\ \bf{ \frac{dy}{dx} = sin \: x(4x) + cos \: x(2 {x}^{2} + 3)} \\ \\ \bf{\frac{dy}{dx} = 4x \: sin \: x + cos \: x(2 {x}^{2} + 3)} \\ \\ \\ \red{hope \: it \: helps \: you}$
