Question

determine derivative of x sin x and x cos x​

Answer 1

Answer:

the derivation of xsinx=cosx

xcosx=-sinx

Explanation:

Answer 2

Answer:

xcosx+sinx and cosx-xsinx respectively

Explanation:

1. let y = xsinx

diff. w. r. t. x

dy/dx = xcosx+sinx.1

so, dy/dx = xcosx+sinx .....ans.

2. let y = xcosx

diff. w. r. t. x

dy/dx = x(-sinx)+cosx.1

so, dy/dx = cosx-xsinx ....ans.
