2. Fourth, fifth, and sixth derivatives of position - Wikipedia

   en.wikipedia.org/wiki/Fourth,_fifth,_and_sixth...

   Snap, [6] or jounce, [2] is the fourth derivative of the position vector with respect to time, or the rate of change of the jerk with respect to time. [4] Equivalently, it is the second derivative of acceleration or the third derivative of velocity, and is defined by any of the following equivalent expressions: = ȷ = = =.

3. Impulse (physics) - Wikipedia

   en.wikipedia.org/wiki/Impulse_(physics)

   The impulse delivered by a varying force is the integral of the force F with respect to time: =. The SI unit of impulse is the newton second (N⋅s), and the dimensionally equivalent unit of momentum is the kilogram metre per second (kg⋅m/s).

4. Dirac delta function - Wikipedia

   en.wikipedia.org/wiki/Dirac_delta_function

   The graph of the Dirac delta is usually thought of as following the whole x-axis and the positive y-axis. [5]: 174 The Dirac delta is used to model a tall narrow spike function (an impulse), and other similar abstractions such as a point charge, point mass or electron point.

5. Motion graphs and derivatives - Wikipedia

   en.wikipedia.org/wiki/Motion_graphs_and_derivatives

   Since the velocity of the object is the derivative of the position graph, the area under the line in the velocity vs. time graph is the displacement of the object. (Velocity is on the y-axis and time on the x-axis. Multiplying the velocity by the time, the time cancels out, and only displacement remains.)

6. Circuit rank - Wikipedia

   en.wikipedia.org/wiki/Circuit_rank

   In graph theory, a branch of mathematics, the circuit rank, cyclomatic number, cycle rank, or nullity of an undirected graph is the minimum number of edges that must be removed from the graph to break all its cycles, making it into a tree or forest. It is equal to the number of independent cycles in the graph (the size of a cycle basis).

7. Flow graph (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Flow_graph_(mathematics)

   There is a close relationship between graphs and matrices and between digraphs and matrices. [9] "The algebraic theory of matrices can be brought to bear on graph theory to obtain results elegantly", and conversely, graph-theoretic approaches based upon flow graphs are used for the solution of linear algebraic equations. [10]

8. Dirac comb - Wikipedia

   en.wikipedia.org/wiki/Dirac_comb

   The graph of the Dirac comb function is an infinite series of Dirac delta functions spaced at intervals of T. In mathematics, a Dirac comb (also known as sha function, impulse train or sampling function) is a periodic function with the formula ⁡ := = for some given period . [1]

9. Green's function - Wikipedia

   en.wikipedia.org/wiki/Green's_function

   In such cases, the solution provided by the use of the retarded Green's function depends only on the past sources and is causal whereas the solution provided by the use of the advanced Green's function depends only on the future sources and is acausal. In these problems, it is often the case that the causal solution is the physically important one.
