In analytic geometry, spatial transformations in the 3-dimensional Euclidean space are distinguished into active or alibi transformations, and passive or alias transformations. An active transformation is a transformation which actually changes the physical position (alibi, elsewhere) of a point, or rigid body, which can be defined in the absence of a coordinate system; whereas a passive transformation is merely a change in the coordinate system in which the object is described (alias, other name) (change of coordinate map, or change of basis). By transformation, mathematicians usually refer to active transformations, while physicists and engineers could mean either. Both types of transformation can be represented by a combination of a translation and a linear transformation. Put differently, a passive transformation refers to description of the same object in two different coordinate systems.On the other hand, an active transformation is a transformation of one or more objects with respect to the same coordinate system. For instance, active transformations are useful to describe successive positions of a rigid body. On the other hand, passive transformations may be useful in human motion analysis to observe the motion of the tibia relative to the femur, that is, its motion relative to a (local) coordinate system which moves together with the femur, rather than a (global) coordinate system which is fixed to the floor.

Active vs Passive Voice in Your Writing
Have you ever noticed how some parts of your writing work really well, while other parts aren’t so great? You can improve those dull sentences if you consider how you structure them. There are two voices in writing: active and passive. In the active voice, the subject of a sentence acts,

The Passive Voice in Italian: Il Passivo
Sometimes rather than making the subject the most important part of the sentence, it is the action itself that is the most relevant. We can achieve this by using the passive voice, communicating that something happened or was done to the subject. Let's see how this works now! Script by Pa
