2. A formula that generates the successive terms of a recursion. From the American Heritage Dictionary of the American Language. |
Step-by-step guide1. Fine the formula for the angle sum of the next polygon after you add another triangle onto one side. S(3) = 180; S(n) = S(n-1) + 180. See the definition of recursion at the left. Possible Problems and
Concerns:Recursion idea needs to be discussed. S(3) = 180; S(n) = S(n-1) + 180. We could use this formula to generate the next polygon. The formula is recursive because it uses preceding terms to define itself. Internet Resources:mste.illinois.edu/m2t2/algebra/concave.gsp| mste.illinois.edu/m2t2/algebra/nonpoly.gsp |
