For example, Isaac Newton employed his binomial theorem to estimate sixteen decimal sites quickly. Early within the 20th century the Indian mathematician Srinivasa Ramanujan designed extremely successful means of calculating pi which were afterwards included into Laptop or computer algorithms. In the early twenty first century pcs have calculated pi to a hundred trillion decimal destinations, and its two-quadrillionth digit when expressed in binary (0).
, and is constrained by Sturm–Liouville principle to take on only sure precise values. It has to be positive, Considering that the operator is adverse definite, so it's easy to write down λ = νtwo, in which ν > 0 is known as the wavenumber.
