Diversas funções e possibilidades de programar novas

Llevo dos años con ella y es perfecta para mi rama de ingeniería, el único defecto que encontré es aprender a usar tantas funciones para diferentes áreas de estudio se vuelve un poco complicado sobre todo si no descubres el botón de ayuda y la rama de opciones de aplicación de funciones.10/10 recomendada IPN.

There are many pros and a few cons to this calculator.Pros: it’s fast, big, rechargeable, high quality, touchscreen, easy to use, you can update the OS, and it has nice buttons that click when pressedCons: the screen resolution could better, and would be good if it had wifiIt is totally worth the money!

HP 35Cが古くなってきたので、新しい電卓を買いました。気に入ったのは、数式の計算ですね。検算もやりやすいので助かります。

This is an outstanding calculator. I got it to replace my TI-nspire CAS after that calculator started dying - and this blows the TI out of the water.First thing you'll notice when you take it out of the package is, this is a seriously sharp-looking device. Jet black case, glossy screen, brushed metal keyboard deck, shiny chrome HP branding. The rocker wheel in the center is metal and has a Zenbook-esque finish(fine concentric rings cut into the surface.)Second, you should note that the glossy screen is 1. In color, which while not necessary, is a very nice touch; and 2. is a touch screen. Point 2 is of special interest; having a touchscreen is so much more elegant than trying to mouse around the screen with a miniscule trackpad, like on the TI-nspire. Tap, I can check the battery level, see the time and date, and see which angle mode it's in. One more tap, and I can switch between degrees and radians at a moment's notice(the Nspire hid this behind a nest of menus). It is also much easier to highlight or place the cursor where you want it.Third, when you go to use it, you'll discover that all the buttons are large, well-labeled and organized, attractively beveled, and feel extremely satisfying under pressure as you type on them. I had no difficulties learning my way around the keypad, even coming from the dramatically different Nspire. There's nothing revolutionary here, but this important part of the calculator was engineered right, with a human user in mind.Fourth, there are a number of apps included with the calculator for different functions. This isn't impressive in the smartphone era, but calculators have lagged far, far behind modern technology for much too long. Examples of these apps include a spreadsheet, an advanced graphing tool, and specialized statistical applications. The notepad can be accessed quite readily with Shift-0(which is clearly labelled for this purpose, so no memorization of that shortcut is needed), and new notes can be added very easily.Fifth, you can recharge this calculator. That's right, no batteries needed, this calculator can be recharged like you would your phone. I hasten to add that, while the charging port(which is also the data port) does not appear at first glance to be mini-USB port, it is compatible with your standard mini-USB phone charger(a cable is provided with the calculator). Simply align the pins first. I say this, because I probably spent 20 minutes trying to figure out how to charge it with a mini-USB cable, without it having a mini-USB port. Again, the port and the cable ARE compatible, just line them up properly.One minor quibble: the calculator lid can be rather difficult to remove from the back(for when it's in use). This will no doubt change as it breaks in through use, but it is still annoying in the meantime.
