摘要
提出一类齐次常微分方程,经过变量替换,给出求积分因子的方法及其求解定理,所得结论是对相关文献问题的扩广。
The article puts forward the concept of homogeneous differential equation Class 1 and gives the method of getting integrating factor and its solver theorem through variable replace,the conclustion of which is an expansion of relavant documents.
