graphing scientific calculato

This a totally new type of advanced programmable calculator! Besides versatile scientific functions, graph functions also make it possible to produce a wide variety of useful graphs to aid in various situations and classes, such as Algebra, Chemistry, General Math, General Science, Geometry, Pre-Algebra, Statistics, and even Trigonometry. Manual calculations can be easily performed following written formulas, a replay function is provided that allows confirmation or correction when something is inputted incorrectly, and you can even input programs by following true algebraic logic! All of this calculative power is wrapped up in a slim and lightweight design, complete with sliding protective cover. The calculator also features a comprehensive and informative instruction manual in both English and Spanish. Graph a parabola, find trigonometric functions in both degrees and radians, and take advantage of four different calculation modes (COMP, BASE-N, SD, and LR), with the Graphing Scientific Calculator.
