Review: My daughter loves it - I bought this as a gift for my daughter and she loves it, she says she didn't understand how she went through high school without it. She's studying computer science and she says this is the best tool she has had to solve her math problems. Great power efficiency, the batteries last a long time in a daily basis use. Overall it is a great instrument, an useful tool for engineering students. At first hand it seems quite complicated to handle, but first impression doesn't last much. It has nice graphics and neat programs, with a large variety of programs and methods, and you can even program them yourself with basic programming skills. Pros: It is somewhat complete, has nice graphics tools and capabilities, the battery last long, it is programmable and has great alternatives for math writings forms. It has all basics and a large variety of methods, and you can find on internet a lot of programs for physics, economics, electrical solving, probabilistic and others Cons: It doesn't have much memory so you can't have many methods programs at once at the same time, meaning if you want to have the electrical circuits solver program and a Lagrange or New-Raph solver, or Gauss or Thevening among others, you have to choose one at the time because it won't be able to storage them all. And there are a few methods missing like Laplace transform, Inverse Laplace, Integral Asymptotics, Chrombach alpha and other advance methods in math, calculus and probabilistic. But the price is excellent
Review: Great Product! Very easy to use. Awesome Functionality. - Great Product! Very easy to use. Awesome Functionality. This is one of the best education investments that i have ever made. Very happy with the purchase. The Calculator is simply great. I understand that in North America teachers and books only uses TI Calculators because is the tool that they have been using for years. Otherwise here in South America most of the High Schools/Universities uses Casio. I use to work with a Casio Graphing FX-7400 for 7 years and was really happy with it. Like my old Casio this new also do the graphing but it does twice as fast!. The FX-9860 Gii is a beast!!. Super fast calculations. The fact that comes with screen light are really nice!. Love the fact that come with 4 size AAA batteries so there is no need to recharge every week like TI or HP color screen calculators. I highly recommend it. Great Price Great Value. Thank you to Casio for the great work building this beast!.
