Sep 21, 2011 · To find the total length of a flat spiral having outer end radius = 15.5 units, inner radius = 5 units & the increase in radius per turn = 0.81 unit, the total No. of turns in the spiral is 7.5. This is an example of an Archimedean Spiral, otherwise known as an arithmetic spiral, where the arms get bigger by a constant amount for each turn.
Get DetailsConstant Function: Let ‘A’ and ‘B’ be any two non–empty sets, then a function ‘ ’ from ‘A’ to ‘B’ is called a constant function if and only if the range of ‘ ’ is a singleton. Algebraic Function: A function defined by an algebraic expression is called an algebraic function.
Get DetailsA classifier is a Supervised function (machine learning tool) where the learned (target) attribute is categorical ("nominal").. It is used after the learning process to classify new records (data) by giving them the best target attribute ().. Rows are classified into buckets. For instance, if data has feature x, it goes into bucket one; if not, it goes into bucket two.
