REFLECTION OF MATH SONG

1.    what you know about math

lyric:

what you know about math
what you know about math
what you know about math
hey, don't you know i represent math league when i add shorty subtract
freshman backpack where i holdin' all my work at
what you know about math
what you know about math
what you know about math
i know all about math
answer's 44 it's real easy cus it's sig figs
you got 45 your answers high you rounded too big
what you know about math
what you know about math
what you know about math
i know all about math
TI-80 silver edition know i'm shinin' dog
extra memory on the back to do my natural log
you know we multiply while memorizing pi
take limits to the sky be sure to simplify
graphing utility it's trigonomety 100 our Math B
don't you cheat off me
distance is rate times time
the sign graph ain't no line
exponential decline
but your score can't beat mine
we're memorizing rate for our math league states
against the math league greats
not gettin many dates
i got to find a mate but girls just playa hate and always make me wait
can't even integrate
don't you know i represent math league when i add shorty subtract
freshman backpack where i holdin' all my work at
what you know about math
what you know about math
what you know about math
i know all about math

From the lyrics, we know that the singer tells that he represents math league when he add shorty subtract. He know all about math that an answer’s 44 and it’s real easy cause it’s sig figs. And then, you can get 45 as your answers high you rounded too big. TI-80 silver edition know that he’s shinin dog. An extra memory on the back to do my natural log. We know that we can multiply while memorizing pi take limits to the sky be sure to simplify graphing utility. Its trigonometry 100 our math B and we may not cheat off. Next distance is rate times time. The sign graph ain’t no line, and then exponential decline but our score can’t beat him. We are memorizing rate for our math league states against the math league grades and not getting many dates so we can represent math league when we add shorty subtract.

2.     Mean, Median, Mode

lyric:

Mean, Median, Mode

Mean, Median, & Mode

How do you find the mean?

Add up the numbers in the data sheet.

Divide the total by the number of items.

The answer is the mean or average.

Mean, Median, & Mode

How do you find the median?

Arrange the numbers in order, from the lowest

to the highest values.

The middle number is the median for an

odd number of items.

The average of two middle numbers is the median

for an even number of items.

Mean, Median, & Mode

Mean, Median, & Mode

How do you find the mode?

Just find the number that repeats most often

And the number is the mode.

If you find no number that repeats most often,

Then there is no mode.

Mean, Median, & Mode

Mean, Median, & Mode

Mean, Median, & Mode

            This song tells about mean, median, and mode of statistic data. Mean is average of statistic data. We can determine mean by way, that is add up the values of all the terms and then divide by the number of the terms. While median of a distribution with a discrete random variable depends on whether the number of terms in the distribution is even or odd. We can determine median by way, that is arrange in order of data and then look for the middle value of data. If the number of terms is odd, then the median is the value of the term in the middle. If the number of the terms is even, then the median is the average of the two terms in the middle, such that the number of terms having values greater than or equal to it is the same as the number of terms having values less than or equal to it. Example, there is a data with even number, that is 1 4 6 2 8 7, to determine median of data, we must arrange in order so that 1 2 4 6 7 8. After that determine middle number, that is 4 and 6 and then 4 added by 6 equals 10 then 10 divided by 2 equals 5. So the median is 5. And while mode of distribution with a discrete random variable is the value of the term that occurs the most often. We can determine mode by way, that is by determining a data or number in which it has a greatest repeats. If the data doesn’t have a repeats so the data doesn’t have mode.

3.     Perimeter Song

lyric:

We know about metres, kilometers, millimeters, and centimeters

We talk about a case big

Now, we now talk about perimeter

With perimeter you have to measure each side

Each side

Add them up

And we find perimeter

Perimeter, that’s perimeter

Perimeter, perimeter, that’s perimeter

This song tells about perimeter of planes, how to learn perimeter a planes such as squares, triangles, rectangles, parallelograms, trapezoid, kite, rhombus, etc. We can determine the perimeter of planes by the way, that is by measuring each side of planes and add them up. For example, the perimeter of a triangle is the sum of its three sides. Perimeter (K) of triangle ABC is formulated as K = AB + AC + BC (if given that three sides of triangle is AB, AC, BC). And then, for the planes such as squares, rectangles, parallelograms, trapezoid, kite, rhombus, etc also are done the same way like triangle, by add of its sides.

RESUME OF VIDEO

DERIVATIVE

Definition of derivative f(x) is a contract between two parties that specifies conditions (especially the dates, resulting values of the underlying variables, and notional amounts) under which payments, or payoffs, are to be made between the partiesand and then there is slope of tangent line at point such as (x, f(x)), (x+h, f(x+h)) with h equals change in x. So that slope is change in y divided by x equals (y2 times y1) divided by (x2 times x1).  The general formula at any point and instead the derivative of fuction.

INTEGER

The integers  are formed by the natural numbers (including 0) (0, 1, 2, 3, ...) together with the negatives of the non-zero natural numbers (−1, −2, −3, ...). Viewed as a subset of the real numbers, they are numbers that can be written without a fractional or decimal component, and fall within the set {..., −2, −1, 0, 1, 2, ...}. For example, 21, 4, and −2048 are integers.

The integers (with addition as operation) form the smallest group containing the additive monoid of the natural numbers. Like the natural numbers, the integers form a countably infinite set.

In algebraic number theory, these commonly understood integers, embedded in the field of rational numbers, are referred to as rational integers to distinguish them from the more broadly defined algebraic integers.

ANGLE

Parts of an Angle :

The corner point of an angle is called the vertex

And the two straight sides are called arms

The angle is the amount of turn between each arm.

Name of Angles :

As the Angle Increases, the Name Changes

1.  Acute angle is an angle that is less than 90°

2.  Right angle is an angle that is 90° exactly

3.  Obtuse angle is an angle that is greater than 90° but less than 180°

4.  Straight angle is an angle that is 180° exactly

5.  Reflex angle is an angle that is greater than 180°.

Complementary angles add up to 90o, while supplementary angles add up to 180o. Angle bisector is a ray that devided an angle two congruent. Two angle wich of equal size it is congruent. Perpendicular lines are intersecting lines that from right angle.
