A free web based math / scientific calculator specially designed for the education environment. It operates in a very similar way to the popular school calculators and so does not need re-learning. The calculator can be blown up to full screen size, making it a useful teaching tool in a classroom setting with a projector. Functions: sin, cos, tan, sin-1, cos-1,tan-1 square root, log10, loge, power of ten, squared, ex Constants: pi, e, root 2 This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.
Students will use a TI82 or TI83 calculator to construct a scatterplot, find the equation of the least-squares regression line for a set of data, find the coefficient of determination, and make predictions by using the line.
