A linear differential equation is often easier to solve than a nonlinear one.
线性微分方程通常比非线性微分方程更容易求解。
Using an integrating factor, we can solve the first-order linear differential equation and obtain an explicit formula for \(y(x)\).
利用积分因子,我们可以解一阶线性微分方程,并得到 \(y(x)\) 的显式表达式。
词源 Etymology
linear 来自拉丁语 linea(线、细绳),引申为“沿直线的、一次的”,在数学里常表示“满足叠加性、齐次性(线性)”。
