In numerical analysis , PERSON@1 's method -LRB- also known as the PERSON@2 method -RRB- , named after PERSON@3 and PERSON@4 , is perhaps the best known method for finding successively better approximations to the zeroes -LRB- or roots -RRB- of a real-valued function .

In math , PERSON@1 's method -LRB- also known as the PERSON@1 -- Raphson method , named after Sir PERSON@3 and PERSON@4 -RRB- is a method for finding the zeroes -LRB- or roots -RRB- of a function whose values are all real .
