Fifth disease, also known as erythema infectiosum and slapped cheek syndrome, [3] is a common and contagious disease caused by infection with parvovirus B19. [4] This virus was discovered in 1975 and can cause other diseases besides fifth disease. [5] Fifth disease typically presents as a rash and is most common in children.
to denote fourth, fifth, sixth, and higher order derivatives. Other authors use Arabic numerals in parentheses, as in (), (), (), …. This notation also makes it possible to describe the nth derivative, where n is a variable. This is written ().
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 = = =.
In mathematics, the derivative is a fundamental tool that quantifies the sensitivity to change of a function's output with respect to its input. The derivative of a function of a single variable at a chosen input value, when it exists, is the slope of the tangent line to the graph of the function at that point.
If the derivative f vanishes at p, then f − f(p) belongs to the square I p 2 of this ideal. Hence the derivative of f at p may be captured by the equivalence class [f − f(p)] in the quotient space I p /I p 2, and the 1-jet of f (which encodes its value and its first derivative) is the equivalence class of f in the space of all functions ...

Fentanyl has made headlines for driving overdose deaths, but the Centers for Disease Control and Prevention (CDC) is warning of the rise of an even deadlier drug. Last year, nearly 70% of all U.S ...
The Toyota Corolla E80 is a range of small automobiles manufactured and marketed by Toyota from 1983 to 1987 as the fifth generation of cars under the Corolla and Toyota Sprinter nameplates. Production totalled approximately 3.3 million, and most models adopted a front-wheel drive layout.
