My experimental Zoomable Tree

Business

I thought I had some notes on business in here somewhere

But, apparently, I didn't

If I had anything to say about business, it would be here.

I just don't have anything to say about business

Education

History

Rome

The Fall of the Roman Republic

Get some more resources for my research paper

Get the scoop on Crassus

WWII

It was the war after the war that ended all wars

Math

Functions

Domain is the members of a function that work with the function (i is not in the domain of any function).

Range is the range of outputs of the function

Vertical line test

If a vertical line passes through more than one point of a graph, it is not a function

Line test for 1-1 relationship

If a line can pass through the graph more than once then the graph is not a one-to-one relationship

Reciprocal functions

Inverted, upside down

Vertical asymptote

A vertical line that is approached by the graph of a function as x approaches a fixed point

I don't understand this

In mathematics, a line or curve that acts as the limit of another line or curve

Geometry

In a circle the product of secant parts = the product of the parts of another secant

45-45 triangle

Two equal sides

Hypotenuse = s*the square root of 2

30-60

Short side is n

long side is n * square root of 3

hypotenuse = 2n

The ratio of the area of something is the ratio of the side of that squared

The volume of a sphere is 4/3 pi r^3

The volume of a cube is s^3

The area of a triangle is 1/2 the base times the height

The base and the height of a triangle must be perpendicular to each other

Opposite angles of an inscribed quadrilateral are supplementary

In a line y = mx + b. m = the slope. b = y-mx

Complex Fractions

is a fraction that contains more than one fraction line

well chosen one

is a fraction (equal to one) that allows you to make the denominators equal so that the fractions could be added

We can use a well chosen one to simplify complex fractions

Shortcut

Whenever a complex fraction has the sum of fractions in the numerator and the denominator, the fraction can be simplified in one step by multiplying above and below by the least common multiple of all denominators

Science

Find the mole in the backyard

Drink a liter of chocolate milk to understand what a liter of something is

On second thought, no.

Practical

Do the laundry

Take out the trash

Eat

Eating is very practical in America

I have 2lrn.com registered but I'm not using it for anything yet

Experiment with Zoomable Tree's

At this point it seems like it is working pretty well
