ns
Syntax
ns(equation, variable)
Description
The name originally stood for n-solve where n was the n in
which is a binomial distribution. ns makes repeated guesses to try to identify non-negative integer solutions to equation. It assumes that there is either a single non-negative solution, or a positive number that separates solutions and non-solutions (e.g. solutions are solutions if and only if they are less than 5.5).
ns can be useful when the built-in solve function fails. In VCE Maths Methods this function is most useful when you get asked a binomial distribution question such as, "How many times does a coin need to be flipped to ensure the probability, that heads was the result at least 22 times, is greater than 0.9?" (The answer is in the first example).
