Math and Arithmetic

As an improper fraction: 126666667/100000000. As an improper fraction: 1 26666667/100000000. The denominator has as many zeroes as the original decimal as digits after the decimal point.

1,600 hours = 66.66 days

Assuming Compound Interest

I(n) = I(0)[1 + r/100]^(n)

Where

I(o) is 231700

r = 3%

n = 5urd 7 mths ( 5.58333....._

Substitute

I(5.583333...) = 231700[1 +3/100]^(5.58333333....)

I(5.583333...) = 231700[1.03]^(5.58333333....)

I(5.583333...) = 231700[1.179436339.... ]

I(5.593333...) = 2732753998...

So interestearned is 41575,3998... ~ 41575.40

Soh, Cah, Toa is an 'aide memoire', for remembering the three trigonometric functions.

Soh ; Sin(angle) = opposite/ hypotenuse.

Cah ; Cos(angle) - adjacent/hypotenuse.

Toa ; Tan(angle) = opposite/ adjacent.

Numbers are infinite, they cannot be measured.

someone else said infinite the real last number is novemtrigintilion cause infinite is not a real number.and if you dont trust me look at this this is how much digits are in novemtrigintilion 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 and add another thousand zeros

The Cylinder.

Remember the Trig. Functions.

Sin(Angle) = opposite / hypotenuse.

Hence algebraically rearranging.

hypotenuse = opposite / [Sin(angle))

NB You MUST know the length of the 'opposite', and the size of the angle.

So if the opposite is of length '2' and the angle is 30 degrees.

Then substituting ;=

hypotenuse = 2 / Sin(30)

From Tables or calculator 'Sin(30) = 1/2 = 0.5'

Hence

hypotenuse = 2 / (1/2) or 2/(0.5)

2/(1/2) = 4 or 2/0.5 = 4

Hence the hypotenuse is '4' units in length.

An angle that has undergone a half turn measures 180 degrees. In terms of geometric representation, this can be visualized as a straight line, where the two rays of the angle point in opposite directions. This configuration divides the plane into two equal halves.

To compare decimals

10.63 & 10.7

Bring both numbers to the same number of decimal places. Two in this case, by inserting a suffix '0'.

Hence

10.63 & 10.70

Drop the Decimal point

1063 & 1070

Drop the prefix '10'

63 & 70

You should recognise that 63 < 70 Hence it follows that 10.63 < 10.7

'8' is in the TENS xolumn , so it would be Eighty.

NB 784

7; hundred as it is the Hundreds column

8 ; as above

4 ; is in the UNITS column

Just add 25 to both sides of the inequality - that way, you will isolate the "x", i.e., solve for "x".

YES!!!!

NB -3.888.... ( recurring to infinity) is also rational.

All numbers are rational except those decimals that recur to infinity AND the decimal digits are NOT in any regular order. .

Example of a rational decimals 0.123123123.... Digits are in a regular order.

Examplkes if irrational numbers.

sqrt(2) = 1.414213562.....

NB An irrational number means it cannot be converted to a ratio/fraction.

The dividend is the number being divided. In a fraction, the top number is the dividend and the bottom number is the divisor.

To compare decimals

6.08 & 6.80

First drop the decimal point

608 & 680 You should be able to recognise that 608 < 680. Hence it follows that 6.08 < 6.80

Let the squares be 'x' & 'y'

Hence

x^(2) - y^(2) = 7

Factor

( x - y)( x + y) = 7

Since '7' is a prime number, we need two number that add to '7' and subtract to '1'.

They are 3, & 4

Hence

(4 - 3) ( 4 + 3) =

1(7) = 7

Algebraically, this is written as

a^(2) + b^(2) = h^(2) (The Pythagorean eq'n).
