Implicit Relations
if f’=0 or f’ DNE –> critical pointif f”>0 concave up
An implicit relation is a mathematical equation in which the dependent variable is not explicitly defined in terms of the independent variable. Instead, the equation relates the independent variable to the dependent variable through an expression that involves both of them. In other words, an implicit relation is a relationship that is not immediately apparent from the way the variables are presented in the equation.
An example of an implicit relation is the equation of a circle:
(x – a)^2 + (y – b)^2 = r^2
In this equation, x and y are the independent variables, and a, b, and r are constants that define the circle’s center and radius. The equation expresses a relationship between x and y that describes all the points on the circle, but the dependent variable y cannot be solved for directly. Instead, both variables must be manipulated algebraically to isolate y on one side of the equation.
Implicit relations are often used in calculus to study curves and surfaces that cannot be expressed as explicit functions. A common technique is to differentiate or integrate the equation implicitly, treating the dependent variable as a function of the independent variable. This can lead to a new equation that relates the derivatives or integrals of x and y, which can provide valuable information about the behavior of the function.
Overall, implicit relations play an important role in mathematical analysis and can help describe many complex phenomena in the natural and physical sciences.
