1、大连东软信息学院课程（单元）项目研究报告系别班级成绩姓名[项目名称]利用Mathmatic解决关于多元函数的实际问题[提交日期]2011年6月3日[项目内容]根据老师给出的题目和数据，利用mathmatic软件解决实际问题，利用Mathmatic软件，首先使用“多元函数你和指令Fit”拟合函数，然后，在使用“多元函数绘图指令Plot3DListplot”画出图像，在求出偏导，从人求出最终答案。并总结[项目目的]为了能够更好地讲数学知识运用于解决实际问题上，将数学更好地与实际生活联系起来，同时也为了让我
2、们对数学知识更深刻的了解，和对数学软件Mathmatic的运用。并且能够在团队共同的努力下完成目标，增加了小组成员的凝聚力，增加团队能力。[研究过程]包括问题的分析，用到的变量符号的说明，研究的详细步骤和过程，研究的结论，对结论优劣的简单分析，改进方向,以及完成本项目对自己学习本课程有哪些促进等.1）首先我们探讨了该怎样进行这个实验，数据调查，分析实验步骤。（2）研究课题有了定向，小组成员就要分工了，对数据分析，处理。（3）使用Mathmatic解决问题，第一步，像Mathmatic中导入数据f={{
