Definition of slope: Rise over Run;
We say the sun “rises” which implies vertical change while we “run” across or “run” cross country which implies a horizontal change.
The letter repesenting slope is “m” think of a
“m”ountain slope.
Zero Slope
The slope of a horizontal line is Z ero.
The first stroke when writing the letter “Z”
Is a horizontal stroke,
Undefined Slope
The slope of a vertical line is said to be
Undefined, we say it has “No” slope.
The first stroke when writing the letter N is a vertical stroke.
When calculating slope, if a Nonzero Number is obtained over a zerO, the fraction N/O vertically spells “NO” which represents uNdefined.
You can’t stand on a beachball.
You can’t divide by zero
VUX & HOY: To determine the type, slope and equations of certain lines
VUX: Vertical, Undefined, X = a
HOY: Horizontal, zerO, Y = b
Absolute Value Function:
Y = |x|
The shape of the graph is a “V” for “value”
Definitions of complementary and supplementary angles:
Complementary Angles: Two angles whose sum is 90 o
Supplementary Angles: Two angles whose sum is 180 o
Alphabetically C comes before S, numerically, 90 comes before 180
C, S 90 o , 180 o
Area and Circumference of a circle:
A = πr 2 Apple pie “r” square
A = π × r × r Apple pie “r” “r”ound
A circle’s area is pi r squarea
C = π d Cherry pie delicious
C = π d Cherry pie-d
To define the trigonometric ratios;
Sinθ = Opposite/Hypotenuse
Cosθ = Adjacent/Hypotenuse
Tanθ = Opposite/Adjacent

To determine where the trig functions are positive:
Starting in the first quadrant and going counter-clockwise in the order the quadrants are numbered;
All functions are positive in quadrant I
Sine is positive in quadrant II
Tangent is positive in quadrant III
Cosine is positive in quadrant IV

Which trig functions are odd, which is even, by the numbers:
1. sine
2. cosine
3. tangent
Since 1 & 3 are odd numbers, sine & tangent are odd functions
Since 2 is an even number, cosine is an even function
For derivatives and antiderivatives of sin & cos, use the wheel in a:
Clockwise rotation for a function’s derivative and
Counterclockwise for a function’s antiderivative.
(equate “counter” with “anti”)

Derivatives sin cos

Antiderivatives sin cos

The Quotient Rule I
If the numerator is “hi” and the denominator is
“ho” and de means the Derivative, we have d(hi/ho) = “ho-de-hi” minus “hi-de-ho over dx ho-ho.
Quotient Rule II
If the numerator is “hi” and the denominator is
“lo” and “de” means the derivative, we have d(hi/lo) = “lo-de-hi” minus ‘hi-de-lo” all over dx lo 2
Measures of Central Tendency
Mean: The sum of the values, divided by the number of values.
The usual method of calculating an “average” by teachers.
Since teachers are “Mean”, this is known as the mean.
Median: The grassy area or wall that runs down the middle of a highway is known as the “Median”. The middle value of a set of values.
Mode: The most frequently occurring value. A four letter word starting with “m-o”. Mode – most.
Primitive Pythagorean Triples: In each case the square of the first value is the sum of the other two values, which differ by one.
3: 4: 5
5: 12: 13
7: 24: 25
9: 40: 41
11: 60: 61
Squaring a number that ends in five:
5 2 = 25
15 2 = 225
25 2 = 625
35 2 = 1225
45 2 = 2025
55 2 = 3025

75

= 4225
= 5625
= 7225
= 9025
= 11025
= 13225
The digit(s) in front of the 5 times the next integer with a 25 on the end gives the product. For example; 65 2 is 6 times 7 is 42 with a 25 on the end yielding 4225.
Converting some fractions to decimals:
Digits over 9 are repeating decimals of that digit. 5/9 = .555…
Digits over 99, 999, etc. are also repeating decimals of those digits. 23/99 = 232323…,
5/99 = .050505…, 5/999 = .005005…
Remembering Pi:

How I want a drink, alcoholic of course after the heavy lectures involving quantum mechanics. All of thy geometry, Herr Planck, is fairly hard…
3.14159265358979323846264
For some easy multiplying:
Never multiply by 4, just double twice.
Instead of trying to multiply by 25, think in terms of twenty-five cent pieces. For example, what is 17 x 25 ? Ask how much would I have if I had 17 quarters? Since 4 quarters make one dollar, 16 would be 4 dollars and the 17 th quarter is another 25 cents, that’s $4.25 or
425 cents or 17 x 25 = 425
