sin \2*x - 3*\/ x /
sin4(3x+2x)\sin^{4}{\left(- 3 \sqrt{x} + 2 x \right)}
sin(2*x - 3*sqrt(x))^4
Detail solution
  1. Let u=sin(3x+2x)u = \sin{\left(- 3 \sqrt{x} + 2 x \right)}.

  2. Apply the power rule: u4u^{4} goes to 4u34 u^{3}

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

    1. Let u=3x+2xu = - 3 \sqrt{x} + 2 x.

    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 ddx(3x+2x)\frac{d}{d x} \left(- 3 \sqrt{x} + 2 x\right):

      1. Differentiate 3x+2x- 3 \sqrt{x} + 2 x term by term:

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

          1. Apply the power rule: xx goes to 11

          So, the result is: 22

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

          1. Apply the power rule: x\sqrt{x} goes to 12x\frac{1}{2 \sqrt{x}}

          So, the result is: 32x- \frac{3}{2 \sqrt{x}}

        The result is: 232x2 - \frac{3}{2 \sqrt{x}}

      The result of the chain rule is:

      (232x)cos(3x2x)\left(2 - \frac{3}{2 \sqrt{x}}\right) \cos{\left(3 \sqrt{x} - 2 x \right)}

    The result of the chain rule is:

    4(232x)sin3(3x+2x)cos(3x2x)4 \left(2 - \frac{3}{2 \sqrt{x}}\right) \sin^{3}{\left(- 3 \sqrt{x} + 2 x \right)} \cos{\left(3 \sqrt{x} - 2 x \right)}

  4. Now simplify:

    2(4x3)sin3(3x2x)cos(3x2x)x- \frac{2 \left(4 \sqrt{x} - 3\right) \sin^{3}{\left(3 \sqrt{x} - 2 x \right)} \cos{\left(3 \sqrt{x} - 2 x \right)}}{\sqrt{x}}


The answer is:

2(4x3)sin3(3x2x)cos(3x2x)x- \frac{2 \left(4 \sqrt{x} - 3\right) \sin^{3}{\left(3 \sqrt{x} - 2 x \right)} \cos{\left(3 \sqrt{x} - 2 x \right)}}{\sqrt{x}}
