Pi, of course, is the ratio of a circle's circumference to its diameter. This number is just slightly over three, and is irrational (it never repeats or terminates).
There are various formulas for deriving pi. You can even obtain an excellent approximation by dropping a pin on a floor of evenly spaced parallel lines. See the associated link for some of the formulas. Note: Machin's formula (using inverse tangents of unit fractions) is calculated in radians. In this respect it is, in effect, a definition of pi in terms of itself. Nevertheless it is a most curious relationship.
π/4 = 4tan-1(1/5) - tan-1(1/239)
More curious yet is the incredible relationship between pi and the natural log e:
eπi = -1, where i is the imaginary square root of -1. i2 = -1.

From what does pi derive from?
Pi is a number (which is 3.14....) which you will always get when you divide a circumference of circle by its diameter...
How do you derive the pi value using integral?
For example, by calculating the surface of a circle, using an integral.
Derive the expression for ripple factor of pi filter?
ripple factor:=21/2 /3 *Xc/XL
Derive the formula for radius if the formula is c equals pi times r squared?
Where pi (~ 3.1416) is represented by π, The formula C= πr2 yields the formula r2 = (C/π) therefore r = square root (C/π). ...which is the same as : r = (C/π)1/2.
Use derive in a sentence?
I derive that this question needs to be moved.
