Calcolatrici scientifiche su cellulare
Cari studenti, tempo fa vi avevo consigliato per i vostri sempre presenti e potentissimi cellulari il software gratuito math4mobile e dalla recensione che avevo fatto lo scorso anno, math4mobile ha subito numerosi miglioramenti, dovete provarlo!
Oggi vi propongo un altro fantastico software: TVH-72g, non ci sono più scuse studente! 
puoi avere gratuitamente la tua calcolatrice scientifica su cellulare.
La potenza del software gratuito che ti propongo renderà il tuo cellulare potente come la mitica HP 49g+ che conservo ancora gelosamente. La risoluzione dei cellulari attuali è superiore alla calcolatrici di un tempo, e con il software tvh-72g potrai studiare trigonometria e funzioni in modo molto interessante.
Paragone tra hp 49g+ e SonyEricson con software tvh-72g
…the use of graphing calculators is being incorporated into the education syllabus of mathematic subjects such as algebra, trigonometry and calculus. Graphing calculators are more expensive than the already costly scientific calculators. And this has raised issues of costs and funding, as well as the logic of burdening students with a US$100 device that’s never use after a semester/term.
Various proposals such as student loans, equipment sharing and rental have surfaced and are being tossed around. To paraphrase One Laptop Per Child (OLPC) association’s message – Students can do a lot of self-learning, especially when they don�t have to leave the (loaned) graphing calculator behind in class. Although PC-based graphing calculator programs exist, the cost of the software licenses and notebooks may still exceed the budget of public schools and disadvantaged students from low-income families / developing countries…

Why A Mobile Phone?
A common handheld device found these days is the mobile phone, and most students have one – even if it’s an entry-level model. Some of these may even be used or refurbished phones. In keeping with the goal of affordability, the mobile phone graphing calculator should not be dependant on premium features such as S60/UIQ Symbian or Windows Mobile that are available only on high-end phones.
Though it maybe unexpected, entry-level mobiles these days do have the processing power and display screen appropriate for emulating a graphing calculator. Take for example a HP 49g+ graphing calculator with a resolution of 131 x 80 pixels, and contrast it with an entry-level Sony Ericsson J300i with a resolution of 128 x 128 pixels. Mid-range cell phones offer even higher resolutions of 176 x 220 pixels (that�s over 3.5 times more pixels than the HP 49g+).
Cost-wise, the commonly recommended graphing calculator for educational purposes is the US$100+ TI-83 Plus, US$130+ TI-84 Plus and the US$150+ HP 49g+. In comparison, an entry-level Sony Ericsson J300i retails for US$75+, or free with a 2-year service agreement.
If anything, CNN reported in January 2006 that Microsoft founder and Chairman Bill Gates believes cell phones are a better way than laptops to bring computing to the masses in developing nations.
