Awesome, powerful, cheap.,
This review is from: Texas Instruments(R) TI-89 Graphing Calculator (Electronics)
Calculus is easy for this graphing calculator. It finds derivative, limits and tons of other calculus. It can graph piecewise functions which is helpful. It can factor and solve quadratics, quartics and higher. Get it; you'll fall in love.
5.0 out of 5 stars
AWESOME CALC,
This review is from: Texas Instruments(R) TI-89 Graphing Calculator (Electronics)
This calculator is a must have if you are taking a college level calculus course. Taking derivatives is super simple as well as all of the other functions this calculator has to offer. Not once did I have to change he battery!
