Question

What is the Differentiation of x^2 Cosx

Answer 1

Hey!!!...Here is ur answer

x^2 cosx

d/dx (x^2 cos x)

=x^2 d/dx (cos x) + cos x d/dx (x^2)

= - sin x .x^2 + 2x.cos x

=2x cosx-x^2sinx

Hope it will help you

Hola User ________________

Here is Your Answer ........
__________________________

Basically here
Y= X^2.Cosx
So actually here using the Product rule we get .......

dy/dx = x^2. d (cosx)/dx + cosx .d (x^2)/dx...
there fore ......
dy/dx = x^2.-sinx + cosx.2x......


so basically we get ....,,
x^2.-sinx+ cosx.2x
