2. 使用SymPy求解 SymPy提供了solve函数,可以直接用于求解方程。下面是使用SymPy求解二次方程的示例代码: from sympy import symbols, Eq, solve def solve_quadratic_sympy(a, b, c): # 定义变量 x = symbols('x') # 定义方程 equation = Eq(a*x2 + b*x + c, 0) # 求解方程 roots = solve(equat...
def solve_quadratic(a, b, c): x = sp.symbols('x') equation = a*x**2 + b*x + c solutions = sp.solve(equation, x) return solutions # 示例 print(solve_quadratic(1, -3, 2)) 通过使用这些方法,您可以在Python中轻松实现求根公式,处理实数和复数根,并利用库来简化计算过程。
将终止多行docstring的"""单独放在一行上 defquadratic(a,b,c,x):"""Solve quadratic equation via the quadratic formula. A quadratic equation has the following form: ax**2 + bx + c = 0 There always two solutions to a quadratic equation: x_1 & x_2. """x_1=(-b+(b**2-4*a*c)*...
We then create another variable, roots, which we set equal to the solve() function. This solve() function takes in 2 parameters. The first parameter is the quadratic equation. The second parameter is the whether the dict, which can be set equal to True or False. If dict is set equa...

Import numpy as np def solve_quad(a,b,c): if a == 0: print('您输入的不是二次方程!') else: delta = b*b-4*a*c x = -b/(2*a) if delta == 0: print('方程有惟一解,X=%f'%(x)) return x elif delta > 0: x1 = x-np.sqrt(delta)/(2*a) x2 = x+np.sqrt(delta)/(...
