Question

Find the derivatives of the following functions with respect to corresponding independent variables:

y = ex sin x

Sum

Solution

y = ex sin x

⇒ y = uv’ + vu’

Now u = ex

⇒ u’ = `("d"u)/("d"x) "e"^x`

v = sin x

⇒ v’ = `("d"v)/("d"x)` cos x

i.e. y’ = ex (cos x) + sin x (ex)

= ex [sin x + cos x]
