## What is pi formula?

π
The formula for the value of pi is the ratio of the circumference of a circle to its diameter. In the ratio form, it is represented as π = Circumference/Diameter.

### What is the value of pi in logarithm?

0.87357
lnelnπ=logelogπ=0.87357 , nearly.

How do you do pi in math?

In basic mathematics, pi is used to find the area and circumference of a circle. Pi is used to find area by multiplying the radius squared times pi. So, in trying to find the area of a circle with a radius of 3 centimeters, π32 = 28.27 cm.

How do you find the value of log 5?

Answer: The value of log 5 is 0.6990 The easiest and fastest way to calculate the value of log 5 is with the help of a logarithmic table. = log 10 – log 2 (Since, log(A/B) = log A – log B)

## How to calculate the logarithm of π 2?

For example lnπ = k + ∑ f(x) or something of this type. where p is prime. The sin function has the beautiful representation as a product sin(x) x = ∞ ∏ n = 1(1 − x2 n2π2). Let x = π 2 and we have the Wallis product formulae for π 2 π 2 = ∞ ∏ n = 1 2n 2n − 1 2n 2n + 1. Taking logarithms of this will give

### How is the logarithm of a number written?

To obtain the logarithm of some number outside of this range, the number was first written in scientific notation as the product of its significant digits and its exponential power—for example, 358 would be written as 3.58 × 10 2, and 0.0046 would be written as 4.6 × 10 −3.

Can a logarithm be converted to a positive base?

Logarithms can also be converted between any positive bases (except that 1 cannot be used as the base since all of its powers are equal to 1), as shown in the of logarithmic laws. Only logarithms for numbers between 0 and 10 were typically included in logarithm tables.

How many pairs of logarithmic functions are there?

As we shall see later with the Change of Base Rule, every pair of logarithmic functions are all but a multiple apart, so that in terms of applications and equation/inequality solving, the three standard logarithms are.generally more than enough to get things going.
