indefinite integral 【數學】不定積分,無定積分。

indefiniteness

Presents a new method for fairing of curves which has a small flexibility based on fitting the derivative of second order of curves . we fit the derivative of second order of curves by a polynomial fitting , then find an indefinite integral of this polynomial to get a approach of curves . otherwise , we discuss the analyze of the error and the optimize of fairing to this arithmetic 提出了一種針對小撓度曲線的逆向曲線光順算法,該算法直接擬合曲線型值點列的二階導數曲線,然后通過兩次積分來反求出光順后的曲線,并對該算法的誤差分析、效果分析、光順優化等問題進行了深入探討。

Definition 2 we shall often use the term indefinite integral in place of antiderivative , that is , the antiderivative of with any constant is called the indefinite integral of ( or ) in , denoted by 在區間上,函數的帶有任意常數項的原函數稱為(或)在區間上的不定積分,記作。
