This resource contains two excel programs with interactive spreadsheets dealing with linear inequalities in one or two variables.
Trial and Improvement
This excel workbook starts with finding square roots then cube roots by trial and improvement. Similar methods are used to solve problems related to areas and volumes. The workbook contains a further four printable worksheets providing further questions for use in the classroom.
Iterative Solutions of Quadratic Equations
This interactive spreadsheet shows calculations and graphs for the iterative method of solving quadratic equations. The graphs can show the stages of the iterations for both of the solutions. There is also a sheet of questions which may be suitable for use in the classroom.
This program was designed to be viewed on a screen with a resolution of 1024 x 768. Users may have to adjust the resolution of their screen for the pages to display as was originally intended. The program uses macros which need to be enabled on a machine.
