Nobody because its a natural fact that the circumference of a circle divided by its diameter is always equal to pi.
2*pi is one complete revolution, i.e. 360 degrees. Sin of 2*pi = sin 360º = 0
Circumference of circle: 7.2*pi units or 7.2 * 3.14159265 = 22.6194671 with rounded values for pi and the resulting circumference.
It's a Greek letter. Greek letters are often used to express constants (mathematical values that don't change).
That was William Jones, from England, in 1705
10log10 (p1 /p0 ) where the pi are power values.
i think it was albert Einstein gave pi its symbol but im not sure.
Pi cannot be expressed exactly as any fraction (including as a fraction of powers of 10, which is what a decimal fraction is). There are an infinite number of place values in the number 'pi'.
infinite number of digits after the decimal point -- pi does not have a finite value.
Because pi = 0.5*tau
There are no repeating strings of values in pi.
To calculate the pI (isoelectric point) value of amino acids, you can use their pKa values. The pI is the pH at which an amino acid carries no net charge. For amino acids with a basic side chain, the pI is the average of the pKa values of the amino and carboxyl groups. For amino acids with an acidic side chain, the pI is the average of the pKa values of the carboxyl and side chain groups.

To calculate the isoelectric point (pI) of a peptide, you need to determine the average of the pKa values of its ionizable groups. This can be done using online tools or by manually calculating the pI based on the amino acid sequence and their respective pKa values.

Cosecant of k*pi radians Secant of 0.5*(2k+1)*pi radiansCotangent of k*pi radianswhere k is an integer.
They gave it a value of about 3 but even today we do not know the exact value of pi
