Answer: sinx + (x+1)cosx

Step-by-step explanation:

To find the derivative of (x+1)sinx, we can use the product rule, which is given by the formula:

[tex]\dfrac{d}{dx}[f(x)g(x)] = f'(x)g(x) + f(x)g'(x)[/tex]

Letting f(x) = x+1 and g(x) = sinx:

  • f'(x) = 1
  • g'(x) = cosx

Now, applying the product rule:

[tex]\dfrac{d}{dx}[(x+1)sinx] = (sinx) + (x+1)cosx[/tex]

The derivative of (x+1)sinx is sinx + (x+1)cosx.
