5*x^atan(x)
Detail solution
  1. The derivative of a constant times a function is the constant times the derivative of the function.

    1. Don't know the steps in finding this derivative.

      But the derivative is

      (log(atan(x))+1)atanatan(x)(x)\left(\log{\left(\operatorname{atan}{\left(x \right)} \right)} + 1\right) \operatorname{atan}^{\operatorname{atan}{\left(x \right)}}{\left(x \right)}

    So, the result is: 5(log(atan(x))+1)atanatan(x)(x)5 \left(\log{\left(\operatorname{atan}{\left(x \right)} \right)} + 1\right) \operatorname{atan}^{\operatorname{atan}{\left(x \right)}}{\left(x \right)}


The answer is:

5(log(atan(x))+1)atanatan(x)(x)5 \left(\log{\left(\operatorname{atan}{\left(x \right)} \right)} + 1\right) \operatorname{atan}^{\operatorname{atan}{\left(x \right)}}{\left(x \right)}
