摘要

摘要:考虑数学分析中一个常用而重要的定积分∫π0sinnxcosmxdx,对m≥0,整数;n≥0情形给出了结果,特别对m和n为非负整数的情形给出了结果,并给出了应用.在理论和应用上,得到了一个很好的工具

Abstract:The important definite integrals in mathematical analysis∫π0sinnxcosm x is put under examination and thus works out the results when m≥0,n≥0 and being an integer in particular with some cases of application given immediately afterwards, which improves to be a nice tool whether in theory or in application．
