Derivatives and Lagsutions to rate or differential equations. However, often we need to do just the opposite, to differentiate or find the slope or rate of change of a variable. The main reason that we would want to find a rate of change in STELLA II is to be able to identify the maximum or minimum value of a variable.

The Law of Mass Actiondry air in the innermost layer, the troposphere, consists of two gases: nitrogen (78%) and oxygen (21%). The remaining air in the troposphere has slightly less than 1% argon and about 0.035% carbon dioxide. Air in the troposphere also holds water vapor in amounts varying from 0.01% by volume at the

The Two-Stage Insect Modeled to know the birth and death rates at each “age class” and the time an individual belongs to that “class.” Thus, in the case of the two development stages EGGS and ADULTS, we need a birth rate, an egg maturation period, an egg survival rate, and an adult death rate.
