Find dy/dx if y=e²×sinx

Answer» we should find \( \frac{\mathrm{d}}{\mathrm{d}x}\mathrm{e}^2 \times \sin x \)

\( \frac{\mathrm{d}}{\mathrm{d}x}\mathrm{e}^2 \times \sin x=\mathrm{e}^2 \frac{\mathrm{d}}{\mathrm{d}x} \sin x=\mathrm{e}^2 \cos x \)

y = e2x sin x

\(\frac{dy}{dx}\) = e2x d/dx sin x + (d/dx e2x) sin x (By UV formula)

= e2x cos x + 2 e2x sin x (By chain rule)

= e2x(cos x+2 sin x)
