函数y=x^3 * 2sin(x^2-x) * cos(x-5)的一阶导数为:
y' = 3x^2 * 2sin(x^2-x) * cos(x-5) + x^3 * 2cos(x^2-x) * (2x-1) * cos(x-5) - x^3 * 2sin(x^2-x) * sin(x-5)
函数y=x^3 * 2sin(x^2-x) * cos(x-5)的二阶导数为:
y'' = 6x * 2sin(x^2-x) * cos(x-5) + 6x^2 * cos(x^2-x) * cos(x-5) - 6x^2 * sin(x^2-x) * sin(x-5) + x^3 * 2cos(x^2-x) * (-2x+3) * cos(x-5) - x^3 * 2sin(x^2-x) * cos(x-5) * (2x-1)
