Difficulties in writing in engineering classes

To be honest, so far I haven’t experienced lots of writing tasks in engineering classes except for the EG1471. The four core modules as everyone takes in my class are math MA1505, physics PC1431, MLE1101 and somehow physics EG1109. For MA1505 and EG1109, the lecturers expect us to use symbols to express the meaning rather than words. Only the PC and MLE modules will ask short questions. For the PC and MLE modules, the difficulty in writing is how to express the inter connection among the variables. So it acquires the ability to express the variables clearly. In order to state them I must know the exactly names of the nouns, laws, theories and principles. For example, there is “totally inelastic collision” but there is no “totally elastic collision”. Instead, it is “elastic collision” representing the meaning of “totally elastic collision”. So I must memorize all the nouns clearly, not mix them up. Besides, the connection within the nouns should also be stated clearly, i.e. whether A is the cause or the effect of B. Therefore, the transition words such as “therefore”, “hence” and “but”, the relationship expressions, “due to the effect of”, “result in” and “result from” are useful. On the back pages of the grammar book there are conjunctive adverbs, subordinating conjunctions and transition signals which can help me in those fields. In the following writing tasks, I will try to use them as much as possible. In other words, try to use more than one kind of sentence structure to express the same meaning.
