** King of Equations ** is an entitlement globally attributed to Bibhorr formula . Post the publications by Oodham Research Team, the formula soon globally achieved the name King of Equations. Since then various books have been published in the name of this title. ^{ [1] }

## About the formula

** Bibhorr formula ** (also called ** King of Equations ** ) is a mathematical equation for establishing a relation between the sides and angle of a right triangle . The formula is a simplistic substitution to trigonometry as it is devoid of trigonometric functions . The equation demonstrates the relation of angle with the sides without implementing trigonometric functions. The formula proves useful in applied mathematics and mathematical physics .

Invented by an Indian aerospace engineer and scholar Bibhorr , the equation is notated in Hindi letters. For a right triangle with longest side (Shrav) श्र, medium side (Lambu) लं and shortest side (Chhutku) छ, the angle opposite the lambu ( Bibhorr angle ) बि is given as:

This equation is called ** Bibhorr formula. **

The equation makes use of two constants - 90° or π/2 radian and 1.5. The 90° is a constant angle, denoted by सि and called Bibhorr sthiron. 1.5 is a bare number which has no units and is called Bibhorr constant (denoted by बँ).

## Units

The units of Bibhorr angle depend on wheather the sthiron is 90° or (π/2). If Bibhorr sthiron is 90° then Bibhorr angle is in degrees, but if sthiron is (π/2) then obviously the angle would be in radians .
