x - sin(x)
xsin(x)x - \sin{\left(x \right)}
x - sin(x)
Detail solution
  1. Differentiate xsin(x)x - \sin{\left(x \right)} term by term:

    1. Apply the power rule: xx goes to 11

    2. The derivative of a constant times a function is the constant times the derivative of the function.

      1. The derivative of sine is cosine:

        ddxsin(x)=cos(x)\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}

      So, the result is: cos(x)- \cos{\left(x \right)}

    The result is: 1cos(x)1 - \cos{\left(x \right)}


The answer is:

1cos(x)1 - \cos{\left(x \right)}
