For adults, a normal resting rate is 60 to 100 beats per minute. Athletes may have a rate as low as 40 bpm because their hearts are trained to efficiently pump blood. If your heart rate is consistently below 60 or above 100, you may have a heart condition, such as arrhythmia.
Integrating Factor. An integrating factor is a function by which an ordinary differential equation can be multiplied in order to make it integrable. For example, a linear first-order ordinary differential equation of type.
A conversion factor originally known as unity bracket method, is a mathematical tool for converting between units of measurement. It is sometimes referred to as a unit multiplier, and consists of a fraction in which the denominator is equal to the numerator. A conversion factor is used to change the units of a measured quantity without changing its value. Because of the identity property of multiplication, the value of a number will not change as long as it is multiplied by one.
