What is Logarithm ?

is the base of the Natural Logarithms (invented by John Napier).

is found in many interesting areas, so it is worth learning about.

The number e frequently occurs in mathematics (especially calculus)

is an irrational constant (like π). Its value is e = 2.718 281 828

value is e = 2.718 281 828 ...

we can also have logarithms to base e. These are called natural logarithms

It was that great mathematician Leonhard Euler who discovered the number e and calculated its value to 23 decimal places.

Euler's identity is an equality found in mathematics that has been compared to a Shakespearean sonnet and described as "the most beautiful equation."

The number e, also an irrational number.

The mathematical constant e is one of the most important numbers in all of mathematics

Math has many important constants,

like pi and i, the imaginary number that is equal to the square root of negative one

But one constant that's equally important, though perhaps less well known, is Euler's constant

The E stands for EDGE (Enhanced Data rates for GSM Evolution) can reach speeds between 120Kbps to 384Kbps.

This was the original iPhone's top data network speed.

Now it's met with a sigh because it means where you're standing doesn't have a 3G or 4G signal.

Leonhard Euler was an 18th century physicist and scholar who was responsible for developing many concepts that are an integral part of modern mathematics.

When you read that, you say "if a to the b power equals x,

then the Log (or Logarithm) to the base a of x equals b."

Log is short for the word Logarithm

Here are a couple of examples: Since 2^3 = 8, Log ( = 3. 2

For the rest of this letter we will use ^ to represent exponents - 2^3 means 2 to the third power.

The Scottish mathematician John Napier published his discovery of logarithms in 1614.

His purpose was to assist in the multiplication of quantities that were then called sines.

The whole sine was the value of the side of a right-angled triangle with a large hypotenuse
