A simple arithmetic calculator was first included with Windows 1.0. [6]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.
At the turn of the millennium, the line between a graphing calculator and a handheld computer was not always clear, as some very advanced calculators such as the TI-89, the Voyage 200 and HP-49G could differentiate and integrate functions, solve differential equations, run word processing and PIM software, and connect by wire or IR to other ...
A Texas Instruments TI-Nspire calculator that contains a computer algebra system. In the 1950s, while computers were mainly used for numerical computations, there were some research projects into using them for symbolic manipulation.

[3] [4] The characteristic equation can only be formed when the differential or difference equation is linear and homogeneous, and has constant coefficients. [1] Such a differential equation, with y as the dependent variable , superscript ( n ) denoting n th - derivative , and a n , a n − 1 , ..., a 1 , a 0 as constants,
Anthony Edwards let a fan in Sacramento know how he felt with an obscene gesture on Friday. That middle finger cost the Minnesota Timberwolves star $35,000. The NBA announced the fine on Sunday ...
A similar but more complicated method works for cubic equations, which have three resolvents and a quadratic equation (the "resolving polynomial") relating and , which one can solve by the quadratic equation, and similarly for a quartic equation (degree 4), whose resolving polynomial is a cubic, which can in turn be solved.
