摘要
应用常微分方程中的积分因子理论证明某些指数公式与对数公式,研究积分因子理论得到一个定理并用于证明某些等式和不等式命题.
The theory of integrating factor in ordinary differential equation was applied to prove some formula of exponent and formula of logarithm. One theorem was obtained by studying the theory of integrating factor and was applied to prove some equality and inequality.
