Parameters (lu, piv) Factorization of the coefficient matrix a, as given by lu_factor. b array. Righthand side. trans {0, 1, 2}, optional. Type of ... Nth prime. Here's how it works: Enter a value for n below, from 1 to 10 12, inclusive. The server will return the nth prime number (counting 2 as the first). Commas and scientific notation (e.g. 1.0e12) are allowed. For example, entering either 1,000,000,000,000 or 1.0e12 will tell you 'The 1,000,000,000,000th prime is 29,996,224,275,833.
