 * (1) ** **Resources links and/or class example**s

**(2) SWOT** (a) Strengths o All calculations are done on your computer, no history in stored on web o Free to use and no registration or username necessary o No software is installed to computer, strictly web-based application o Easy to use calculator that follows order of operations for complex operations o Limited screen buttons to click, numbers can be entered from keypad o Insertion/deletion of numbers without retyping o Keeps a history of calculations on screen until you remove them o Conversion factors are stored for easy use. o Allows you to copy history and change preferences

**(b) Weaknesses** o Interface is really plain and unattractive. o No instructions for use, so if student is unfamiliar with calculator input formats they will not know what a parameter is o No graphing tools o Help file is overlaid by Google ads making it difficult to read. o Cos 90 degrees comes out to 6.123233995736766e-17 instead of 0. This will confuse many students. o Copy all history is only supported on IE

**(c) Opportunities** o Quick calculations for students without scientific calculators available o Conversion tool can help because they don’t need the factor memorized

**(d) Threats** o I cannot see any apparent threats to using this tool. >Could become a crutch for students who are not yet allowed to use calculators in class.

**(3) Ideas for the classroom** · Use as an aide in a computer lab when doing math work. · Use to check math homework or conversion problems. >Use as a tool to supplement inverse trigonometric functions, as it relates to the domain and range restrictions.
