What is actor in sequence diagram?
Space and AstronomyActors – An actor in a UML diagram represents a type of role where it interacts with the system and its objects. It is important to note here that an actor is always outside the scope of the system we aim to model using the UML diagram. Do sequence diagrams need an actor? It is
What properties are different in enantiomers?
Space and AstronomyEnantiomers differ only in the properties that are chiral: ➢ direction of rotation of plane polarized light, ➢ their rate of reaction with chiral reagents, ➢ biological activity and taste. Which property of enantiomers is not identical? Enantiomers have identical chemical and physical properties and are indistinguishable from each other except for the direction of
What is waxing and waning of the moon?
Space and AstronomyA waxing moon is a moon that gets more sunlight on it as the days go by. It is after we experience a new moon up to a full moon. A waning moon is after the full moon and will remain waning until we again experience a new moon. How do you tell if a
What is end behavior model calculus?
Space and AstronomyThe end behavior of a function f describes the behavior of the graph of the function at the “ends” of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the
Why alternate interior angles are congruent?
Space and AstronomyThe alternate interior angles theorem states that, the alternate interior angles are congruent when the transversal intersects two parallel lines. Hence, it is proved. Alternate interior angles can be calculated by using properties of the parallel lines. How do you prove alternate interior angles are congruent? Video quote: Remember the corresponding angle postulate tells us
What is the meaning of tidal theory?
Space and AstronomyDefinition of tidal theory 1 : a theory of the evolution of a celestial body that is based on the action of tidal forces specifically : such a theory explaining the moon’s evolution. 2 : the theory of the present ocean tides. Who made the tidal theory? Galileo Galileo tried to use his tidal theory
Does the moon have Lagrange points?
Space and AstronomyThere are five such points, labelled L1 to L5, all in the orbital plane of the two large bodies, for each given combination of two orbital bodies. For instance, there are five Lagrange points L1 to L5 for the Sun–Earth system, and in a similar way there are five different Lagrange points for the Earth–Moon
How do you find the slope of similar triangles?
Space and AstronomyDo similar triangles have same slope? Because the two triangles are similar, their hypotenuses will always have the same slope. It is common to see one triangle nested inside of another similar triangle. In this situation, the two triangles share one of the angles. Two of the sides are part of the larger triangle. What
How do you take the derivative of inverse sine?
Space and AstronomyHow is the derivative of inverse sine derived? Video quote: And that's this part right here sine squared of Y. So you can take this cosine of Y which is what we have down here and once we rewrite it as the square root of 1 minus x squared. What is the derivative of inverse
What is a mark that connects two points?
Space and Astronomy2 Line A mark that connects two points. Think of it in math terms, what do you call a line in math? We define line as a mark that connects two points. What is a mark made to connect two points called? Terms in this set (14) line. One definition of this element is “a
