1 www.superfunpage.ch Every prospective graduate engineer is taught right from the start, for example, not to represent the sum of two variables in the form. This shape is banal and shows bad style. First lesson in applied mathematics

2 www.superfunpage.ch Even at the beginning of the semester you know: and continue to Also, is obvious to the knowledgeable reader

3 www.superfunpage.ch Therefore, it can be expressed in a much more scientific way.

4 www.superfunpage.ch Further information can be viewed immediately: and

5 www.superfunpage.ch Therefore it can now be simplified to the following form:

6 www.superfunpage.ch If we take into account that and we remember that the inverse of the transposed matrix is ​​the transpose of the inverse, we can achieve a further simplification under the restriction of a one-dimensional space by introducing the vector, where:

7 www.superfunpage.ch If you now connect with, the result is

8 www.superfunpage.ch Inserted in our expression results in the following simplified form: Now at the latest it is obvious that this equation is much clearer and easier to understand than

9 www.superfunpage.ch There are a number of other methods to simplify the equation in other ways. However, these are only dealt with once the prospective graduate engineer has understood the simple principles applied here.
