of any circle’s circumference to its diameter in the Euclidean plane; this is the same value as the ratio of a circle’s area to the square of its radius. It is approximately equal to 3.14159265 in the usual decimal notation. Many formulae from mathematics‚ science‚ and engineering involve π‚ which makes it one of the most important mathematical constants. π is an irrational number‚ which means that its value cannot be expressed exactly as a fraction m/n‚ where m and n are integers. Consequently

Zero is a number and a digit used in mathematics to represent that number in numerals. Zero is not a natural number but it is the smallest whole number. There are two important uses of zero. Firstly‚ in place value number system it is used as empty place indicator. Hence‚ in this number‚ 5102‚ the positions of 5 and one are correct just because of the inclusion of zero. Five is denoting a thousandth place value. Similarly if we omit zero from 5102 that is 512‚ then 5 denote a hundredth place value

MATHEMATICS OF INVESTMENT Simple Interest If you borrow a car from a car rental company or if you live in someone else’s house or apartment‚ you have to pay rent. Like paying rent for the use of a car or a house‚ you also have to pay rent for the money you borrowed. This is called interest. People like Marco earn by charging interest on loans. Banks earn most of their income from the interest that people pay for the amounts they borrow. How much interest one has to pay depends on three factors:

MATH 101 Mathematics Autobiography Assignment My name is Casey Nicole Layton‚ and I am nineteen years of age. I was born in Pittsburgh‚ Pennsylvania on January 20th‚ 1995. My parents used to call me an ice princess when I was little‚ and they always told me the same story when I’d ask how I had acquired that name. When they tried to bring me home from the hospital‚ we got stuck in the family car during a huge blizzard and the winter chill got to me‚ and they used this fairytale-like story to explain

Science practical report (The relationship between voltage and Current) Aim: To find out how current‚ voltage and résistance in a electric circuit are related. Hypothesis The reading for both voltmeter and ammeter will have complete different results in relationship to the resistor‚ voltage and current. That voltmeter will have a higher reading than ammeter. Materials * Power pack * Piece of nidrome * 50 cm long or a resistor * Hear proof mat * 6 connecting wires *

Speed Practical Report Aim – To determine if different forms of movement for the same distance will affect the average speed. Hypothesis – Moving in different directions will affect the average speed because there are different actions involved in running‚ jumping and grapevines. Jumping involves a longer motion which will take the longest time because a jump covers the least amount of distance per second meaning a slower average speed. Running will have the fastest speed because this takes the least
