Detail solution
  1. Let u=sin(ex2)u = \sin{\left(e^{x^{2}} \right)}.

  2. The derivative of log(u)\log{\left(u \right)} is 1u\frac{1}{u}.

  3. Then, apply the chain rule. Multiply by ddxsin(ex2)\frac{d}{d x} \sin{\left(e^{x^{2}} \right)}:

    1. Let u=ex2u = e^{x^{2}}.

    2. The derivative of sine is cosine:

      ddusin(u)=cos(u)\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}

    3. Then, apply the chain rule. Multiply by ddxex2\frac{d}{d x} e^{x^{2}}:

      1. Let u=x2u = x^{2}.

      2. The derivative of eue^{u} is itself.

      3. Then, apply the chain rule. Multiply by ddxx2\frac{d}{d x} x^{2}:

        1. Apply the power rule: x2x^{2} goes to 2x2 x

        The result of the chain rule is:

        2xex22 x e^{x^{2}}

      The result of the chain rule is:

      2xex2cos(ex2)2 x e^{x^{2}} \cos{\left(e^{x^{2}} \right)}

    The result of the chain rule is:

    2xex2cos(ex2)sin(ex2)\frac{2 x e^{x^{2}} \cos{\left(e^{x^{2}} \right)}}{\sin{\left(e^{x^{2}} \right)}}

  4. Now simplify:

    2xex2tan(ex2)\frac{2 x e^{x^{2}}}{\tan{\left(e^{x^{2}} \right)}}


The answer is:

2xex2tan(ex2)\frac{2 x e^{x^{2}}}{\tan{\left(e^{x^{2}} \right)}}
