  2. Time derivative - Wikipedia

    en.wikipedia.org/wiki/Time_derivative

    Many other fundamental quantities in science are time derivatives of one another: force is the time derivative of momentum; power is the time derivative of energy; electric current is the time derivative of electric charge; and so on. A common occurrence in physics is the time derivative of a vector, such as velocity or displacement. In dealing ...

  3. 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 = = =.

  4. Derivative test - Wikipedia

    en.wikipedia.org/wiki/Derivative_test

    The higher-order derivative test or general derivative test is able to determine whether a function's critical points are maxima, minima, or points of inflection for a wider variety of functions than the second-order derivative test. As shown below, the second-derivative test is mathematically identical to the special case of n = 1 in the ...

  5. Jerk (physics) - Wikipedia

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

    Further time derivatives have also been named, as snap or jounce (fourth derivative), crackle (fifth derivative), and pop (sixth derivative). [12] [13] The seventh derivative is known as "Bang," as it is a logical continuation to the cycle. The eighth derivative has been referred to as "Boom," and the 9th is known as "Crash."

    If the fluent ⁠ ⁠ is defined as = (where ⁠ ⁠ is time) the fluxion (derivative) at = is: ˙ = = (+) (+) = + + + = + Here ⁠ ⁠ is an infinitely small amount of time. [6] So, the term ⁠ ⁠ is second order infinite small term and according to Newton, we can now ignore ⁠ ⁠ because of its second order infinite smallness comparing to first order infinite smallness of ⁠ ⁠.

  7. Unemployment insurance in the United States - Wikipedia

    en.wikipedia.org/wiki/Unemployment_insurance_in...

    Unemployment insurance is funded by both federal and state payroll taxes. In most states, employers pay state and federal unemployment taxes if: (1) they paid wages to employees totaling $1,500 or more in any quarter of a calendar year, or (2) they had at least one employee during any day of a week for 20 or more weeks in a calendar year, regardless of whether those weeks were consecutive.

    A MEC is a life insurance policy that has received excessive deposits over the first seven years of its existence. Violating the seven-year rule produces an irrevocable change to the policy and it ...

  9. Second partial derivative test - Wikipedia

    en.wikipedia.org/wiki/Second_partial_derivative_test

    Thus, the second partial derivative test indicates that f(x, y) has saddle points at (0, −1) and (1, −1) and has a local maximum at (,) since = <. At the remaining critical point (0, 0) the second derivative test is insufficient, and one must use higher order tests or other tools to determine the behavior of the function at this point.
