      这将测试函数 f(x) = 2x^2 - 3x -2 = (2x+1)(x-2)

    • testQuintic

      public void testQuintic()
      这将测试五次函数 f(x) = x^2(x-5)(x+3)(x-1) = x^5 - 3x^4 -13x^3 + 15x^2

    • testfirstDerivativeComparison

      public void testfirstDerivativeComparison()
      通过比较测试 firstDerivative 函数

      这将测试函数 f(x) = x^3 - 2x^2 + 6x + 3, g(x) = 3x^2 - 4x + 6 和 h(x) = 6x - 4
