Question

How do you find the differential `dy` of the function `y=xsinx`?

Answer 1

`dy=(sinx+xcosx)dx`

Explanation:

First, we need to differentiate this function using the product rule:

`dy/dx=sinx+xcosx`

Now we can multiply the derivative by `dx` to get `dy` on its own:

`dy=(sinx+xcosx)dx`
