This document provides examples and explanations of using Pascal's triangle to expand binomial expressions. It shows how to:
1) Expand binomial expressions like (x + 1)5 and (x - y)8 using the appropriate row of Pascal's triangle as coefficients.
2) Determine missing coefficients in expansions like (x + y)7.
3) Compare directly multiplying factors to using the binomial theorem to expand expressions like (x - 5)4.
4) Expand various binomial expressions like (x + 2)6, (x2 - 3)5, and (-2 + 2x)4 by applying the binomial theorem.
Absolute value 1
The document defines absolute value as the non-negative value of a real number without regard to its sign. It provides examples of calculating the absolute value of numbers and ordering numbers by their absolute values. Absolute value represents the distance of a number from zero on a number line. The document suggests absolute values are useful and provides homework problems for further practice.
Trig identities #1 solutions
The document is a notebook on trigonometric identities from November 27, 2012. It covers over 25 pages and explores over a dozen important trig identities including the sum, difference, double-angle, and half-angle formulas as well as identities involving trig functions of multiples of an angle. Examples are provided to demonstrate how to use the identities to simplify trigonometric expressions.

The document discusses logarithmic functions and their properties when graphed. It explores the relationship between logarithmic and exponential functions by showing their inverse graphical relationship. Examples are shown of logarithmic functions graphed along with their corresponding exponential functions to illustrate how changing variables in one function results in a reflection change in the other graphed function.

Quiz solultions absolute value
This document provides solutions to an absolute value quiz. It explains the steps to solve absolute value equations such as |x-3| = 5 by splitting it into cases of x-3 ≥ 0 and x-3 < 0. It also shows how to evaluate and simplify expressions involving absolute values, such as |x| + 4, by considering x as either positive or negative.
27th september 2012 summ and difference identities
This document discusses sum and difference identities for trigonometric functions. It explains that the sum and difference of two trig functions can be rewritten in terms of a single trig function using trigonometric identities. Examples are provided to show how trig identities can be used to simplify expressions involving sums or differences of trig functions into a single trig function of the sum or difference of the angles.

The document discusses reflections of functions across the x-axis and y-axis. Reflecting across the y-axis causes the x-values to become opposite, resulting in the function y=f(-x). Reflecting across the x-axis causes the y-values to become opposite, resulting in the function y=-f(x). The document provides examples of determining the reflected point for a given point on a function, and instructs the reader to sketch both the original and reflected graphs.
