| Abstract: | This paper introduces typical methods of applying Mathcad,a mathematic software package,in the physics experiments data processing.This introduction is based on two examples,solving the partial differential expression of measurement results with unidentified degree,and fitting a curve with the least square method.Results show that Mathcad has powerful sign calculation capabilities and comprehensive functions of data analysis and processing,which makes itself more suitable in college physics experiment data processing than other types of software. |
