(log(sin(x)^2)/log(2))^3
Detail solution
  1. Let u=log(sin2(x))log(2)u = \frac{\log{\left(\sin^{2}{\left(x \right)} \right)}}{\log{\left(2 \right)}}.

  2. Apply the power rule: u3u^{3} goes to 3u23 u^{2}

  3. Then, apply the chain rule. Multiply by ddxlog(sin2(x))log(2)\frac{d}{d x} \frac{\log{\left(\sin^{2}{\left(x \right)} \right)}}{\log{\left(2 \right)}}:

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

      1. Let u=sin2(x)u = \sin^{2}{\left(x \right)}.

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

      3. Then, apply the chain rule. Multiply by ddxsin2(x)\frac{d}{d x} \sin^{2}{\left(x \right)}:

        1. Let u=sin(x)u = \sin{\left(x \right)}.

        2. Apply the power rule: u2u^{2} goes to 2u2 u

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

          1. The derivative of sine is cosine:

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

          The result of the chain rule is:

          2sin(x)cos(x)2 \sin{\left(x \right)} \cos{\left(x \right)}

        The result of the chain rule is:

        2cos(x)sin(x)\frac{2 \cos{\left(x \right)}}{\sin{\left(x \right)}}

      So, the result is: 2cos(x)log(2)sin(x)\frac{2 \cos{\left(x \right)}}{\log{\left(2 \right)} \sin{\left(x \right)}}

    The result of the chain rule is:

    6log(sin2(x))2cos(x)log(2)3sin(x)\frac{6 \log{\left(\sin^{2}{\left(x \right)} \right)}^{2} \cos{\left(x \right)}}{\log{\left(2 \right)}^{3} \sin{\left(x \right)}}

  4. Now simplify:

    6log(sin2(x))2log(2)3tan(x)\frac{6 \log{\left(\sin^{2}{\left(x \right)} \right)}^{2}}{\log{\left(2 \right)}^{3} \tan{\left(x \right)}}


The answer is:

6log(sin2(x))2log(2)3tan(x)\frac{6 \log{\left(\sin^{2}{\left(x \right)} \right)}^{2}}{\log{\left(2 \right)}^{3} \tan{\left(x \right)}}
