Legendre expansion theorem
NettetThe prime number theorem is an asymptotic result. It gives an ineffective bound on π(x) as a direct consequence of the definition of the limit: for all ε > 0, there is an S such that for all x > S , However, better bounds on π(x) are known, for instance Pierre Dusart 's. NettetVarying the individual Legendre coefficients, using unnormalized Legendre polynomials. Figure 15.2.3 below allows you to see the effect of varying the Legendre coefficients …

NettetNext to a power series, the classical Legendre series offers the simplest method of representing a function using polynomial expansion means. In 1862, Neumann … In mathematics, Legendre's formula gives an expression for the exponent of the largest power of a prime p that divides the factorial n!. It is named after Adrien-Marie Legendre. It is also sometimes known as de Polignac's formula, after Alphonse de Polignac.
