Is it important to represent the electrical field and the magnetic flux with vectors?
It is imperative to use vectors at all times. It can be verified with the right-hand rule that they are both key components that affect the direction in which the electrons flow.
What is the necessity of cis and trans molecules?
Cis and trans molecules are very important in living species. In fact, living bodies recognize mostly trans molecules because they are optimized to take up less energy in 3-dimensional space.
What does an integral physically represent?
An integral physically represents the area under a curve. It represents the infinitesimal sum of the area of rectangles that are present under the function's curve.
