我们来一步步分析~ 我们先令c = -c,转化为我们熟悉的线性方程ax + by = c.然后: ①用扩展欧几里德找到一组解(x0,y0),这个很简单。但也有需要注意的地方,比如a,b,c=0的情况需要特殊注意一下,虽然扩展欧几里德可以解出a,b,c为任何值的一组解,但是这些情况在寻求解的个数的时候还是和一般方程不太一...
②我们也知道方程的通解为: x = x0 + kb' (1); y = y0 - ka' (2) ; (b' = b/gcd(a,b), a' = a / gcd(a,b) ). 那么sgu 106就是求在范围内k能取几个: ③将x1,x2带入上面(1)方程求出k1,k2 (k1 < k2); 同理将y1, y2带入上面(2)方程求出k3, k4 (k3 < k4).则 ans...

Equation 7 where u has zero divergence and is parallel to D; that is, u . n = 0 on D. We use the theorem without proof. For details and a proof of this theorem, refer to Section 1.3 of Chorin and Marsden 1993.This theorem states that any vector field can be decomposed int...
Some matrices arenearly singular, and despite the fact that an inverse matrix exists, the calculation is susceptible to numerical errors. Thecondfunction computes thecondition number for inversion, which gives an indication of the accuracy of the results from matrix inversion. The condition number ran...
What function __y = f(x)__ is the solution to the differential equation __y' = 6y__ with the condition that __f(0) = -0.4__? What to do when a differential equation doesn't have a solution? Which of th...
In the xy - plane, the line with equation ax + by + c = 0, where abc≠ 0, has slope . What is the value of b ? (1) a = 4 (2) c = −6 选项: 答案: A 经典答疑 发起提问 提问: 点此查看答疑 这个题abc不等于0只能说明任意一个数不为零,直线有斜率只能说明B不等于0,但是...
