12X1 T05 01 inverse functions (2010)
The document discusses inverse functions. An inverse function f^-1(x) is obtained by interchanging x and y in the original function f(x). For f^-1(x) to be a function, there must be a unique y-value for each x-value. A function and its inverse are reflections across the line y=x. The domain of f(x) is the range of f^-1(x), and vice versa. To test if an inverse function exists, use the horizontal line test or check if rewriting the inverse relation as y=g(x) yields a unique expression for y. If an inverse function exists, f^-1(f(x)) = x and f(
Inverse functions and relations
1) An inverse function f^-1 interchanges the x and y values of the original function f.
2) For a function to have an inverse, it must be one-to-one, meaning each x maps to a single y and vice versa.
3) To find the inverse of a function algebraically, interchange x and y and solve for y. The graph of an inverse is the reflection of the original graph across the line y=x.

Partial Derivatives
Partial derivatives are used to calculate the rate of change of a function of two or more variables with respect to one variable, while holding the other variables constant. The partial derivative of z with respect to x, denoted ∂z/∂x, is defined as the limit of the difference quotient as Δx approaches 0, while holding y constant. Similarly, the partial derivative of z with respect to y, denoted ∂z/∂y, is defined as the limit of the difference quotient as Δy approaches 0, while holding x constant.

This document discusses generative and discriminative classifiers. Generative classifiers model the joint distribution of data and labels, while discriminative classifiers directly model the conditional probability of labels given data. Naive Bayes is an example of a generative classifier, while logistic regression is a discriminative classifier that directly models the probability of a label given input features. The document provides mathematical details on naive Bayes, logistic regression, and how logistic regression can be trained to maximize conditional likelihood through gradient descent.
Jacobians new
Changing variable is something we come across very often in Integration. There are many
reasons for changing variables but the main reason for changing variables is to convert the
integrand into something simpler and also to transform the region into another region which is
easy to work with. When we convert into a new set of variables it is not always easy to find the
limits. So, before we move into changing variables with multiple integrals we first need to see
how the region may change with a change of variables. In order to change variables in an
integration we will need the Jacobian of the transformation.
Partial differentiation B tech
A partial differential equation contains one dependent variable and more than one independent variable. The partial derivatives of a function f(x,y) with respect to x and y at a point (x,y) are represented as ∂f/∂x and ∂f/∂y. Higher order partial derivatives can be found by taking partial derivatives multiple times with respect to the independent variables. The chain rule can be used to find partial derivatives when the dependent variable is a function of other variables that are themselves functions of the independent variables.
Inverse functions 1.6
The document discusses functions and their inverse functions. It provides an analogy that functions are like dye that colors eggs, and the inverse "undoes" the dye by bleaching the egg. The inverse of a function undoes what the original function did. For the square function f(x)=x^2, its inverse is the square root function. Graphically, the inverse function switches the x and y values of a point. The graphs of a function and its inverse are mirror images across the line y=x. Examples are provided to demonstrate finding the inverse of functions by switching x and y and solving for y.
Inverse Functions
1) The document discusses finding the inverse of functions by interchanging the x and y variables and solving for y. It provides examples of finding the inverses of f(x)=3x-7 and g(x)=2x^3+1.
2) It also discusses verifying inverses by checking if the composition of a function and its inverse equals x. And finding inverses of functions with restricted domains, including an example of f(x)=sqrt(x+4).
3) Finally, it discusses the relationship between a function being one-to-one and having an inverse function, both algebraically and graphically.
Engr 371 final exam august 1999
The document is a final exam for an engineering course covering several topics in probability and statistics. It contains 7 multi-part questions testing concepts such as Benford's Law, probability distributions including normal, Poisson, and Rayleigh distributions, sampling and descriptive statistics. Students are allowed basic calculators and materials but no outside resources to solve the problems and show their work.
Exponential functions
The document discusses exponential functions of the form f(x) = ax, where a is the base. It defines exponential functions and provides examples of evaluating them. The key aspects of exponential graphs are that they increase rapidly as x increases and have a horizontal asymptote of y = 0 if a > 1 or y = 0 if 0 < a < 1. Examples are given of sketching graphs of exponential functions and stating their domains and ranges. The graph of the natural exponential function f(x) = ex is also discussed.
Integration+using+u-substitutions
This document discusses integration using u-substitutions. It covers power rule integration, trigonometric integration, integrands, and separable differential equations. Specific topics include finding derivatives using the power rule, calculating derivatives and integrals of trigonometric functions, odd and even integrands, and solving separable differential equations. Worked examples and frequently asked questions are provided for each topic.
1.6 inverse function (optional)
The document discusses inverse functions. It begins by defining a function f(x) that takes an input x and produces an output y. It then introduces the concept of finding the inverse of this function - the reverse procedure that takes the output y and finds the corresponding input(s) x. This reverse procedure may or may not be a function. For it to be a function, f(x) must be one-to-one, meaning that different inputs x produce different outputs y. The document provides examples and diagrams to illustrate one-to-one functions and their inverses. It concludes that if f(x) is one-to-one, then its inverse function f-1(y) is well-defined

Lesson 2: A Catalog of Essential Functions
linear, quadratic, cubic, power, trigonometric, exponential, and logarithmic functions are discussed.
Partial Differentiation & Application
The document discusses partial differentiation and its applications. It covers functions of two variables, first and second partial derivatives, and applications including the Cobb-Douglas production function and finding marginal productivity from a production function. Examples are provided to demonstrate calculating partial derivatives of various functions and applying partial derivatives in contexts like production analysis.

Mc ty-explogfns-2009-1
Exponential and logarithm functions are important in both theory and practice. They examine the graphs of exponential functions f(x)=ax where a>0 and logarithm functions f(x)=loga(x) where a>0. It is important to practice these functions so their properties become intuitive. Key properties include exponential functions where a>1 increase rapidly for positive x and 0<a<1 increase for decreasing negative x, and both pass through (0,1). The natural logarithm function f(x)=ln(x) is particularly important.
Eigenvalues
Eigenvalues and eigenfunctions are key concepts in linear algebra. An eigenfunction is a function that when operated on by a linear operator produces a constant multiplied version of itself. The constant is the corresponding eigenvalue. Eigenvalues are the solutions to the characteristic polynomial of the linear operator. Eigenfunctions are not unique as any constant multiple of an eigenfunction is also an eigenfunction with the same eigenvalue. The spectrum of an operator is the set of all its eigenvalues.
