# What is the meaning of In in mathematics?

In is a log function that is used in mathematics as In(x) that represent a value equivalent to In(e)

What is the natural logarithm of a number?

Natural logarithm In(x) is the log of that number to the base of a constant “e”

The natural logarithm of a number is usually written as In(x) where x represents any number to base e

It also be written as the log of x to base e

Where e is equivalent to 2.718281828

“In” is the natural logarithm of a number and is equivalent to the log of a number to base e where e is equal to

The logarithm of a number is the power or exponent by which another number must be raised to get an equivalent value

Example

1. Differentiate y=in(2x+1)
2. Integrate y=in(2x+19)

Common Logarithm refers to the log of a number expressed to base 10

While natural logarithm is the log of a number expressed to base e, it is the power whereby e should be raised to be equivalent to N

How is log different from ln?

Log can be to any base while ln is strictly to base e where e is a constant number 2.718281828459

Natural logarithm rules

1.  In(ab) =In(a) + in(b)
2. In(1/a) =-In(a)
3. In(e)=1
4. What does in mean in math?

In is the natural logarithm of a number to base e

• What means in?
