a.output解集为空的原因是:这些方程中的系数等都是很复杂的小数,所以这个方程组无法用solve得到自洽的精确的解!此时只有自己在纸上解方程组!!! b.提示信息:“Solve::ratnz: Solve 无法求解具有不精确系数的系统. 答案是通过求解相应的精确系统并且将结果数值化处理得到的.”的含义为:从其他地方复制来的1.59845等...
首先,我们需要编写一个名为`Solve_Equations`的函数,该函数接受两个参数:一个是方程组,另一个是变量。然后,我们需要解析这个方程组,找到所有可能的解。 解析步骤如下: 1. 将方程组按照等号右边的表达式进行分类,例如,如果方程组中有两个方程,第一个方程的右边是一个常数,第二个方程的右边是一个变量,那么这两...
derivative. To solve this equation with `odeint`, we must first convert it to a system of first order equations. By defining the angular velocity ``omega(t) = theta'(t)``, we obtain the system:: theta'(t) = omega(t) omega'(t) = -b*omega(t) - c*sin(theta(t)) ...

AIMpy is a solver for Schrdinger-like differential equations using asymptotic iteration method (AIM). To confirm that the code works seamlessly, it has been shown through the paper, with recalculation of some previously studied eigenvalue examples, that the code can very well reproduce their ...
To solve this system of two equations for the two unknowns,xxandyy, first import the SymPy package. From the SymPy package, the functionssymbols,Eqandsolveare needed. In [1]: fromsympyimportsymbols,Eq,solve Next, create two SymPy symbols objects,xxandyy. As shown in a previous section, ...
