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.
Integrating Factors An integrating factor is any function that is used as a multiplier for another function in order to allow that function to be solved; that is, using an integrating factor allows a non-exact function to be exact. Integrating factors are most often used in first-order differential equations, but may also be used in higher-order equations as well.
