Scientific Graphing Calculator Screenshots

Description

Features:

1) Scientific Calculator. A lot of thought has gone into the design of the keyboard, which gives you everything you need while keeping the keys as large as possible. Available functions include the following:

the usual arithmetic functions and exponentiation.
square root, cube root, nth root, natural log, log base 10, log of arbitrary base, absolute value, factorial, permutations (nPr), combinations (nCr), modulus, random integer, bell curve, cumulative normal distribution.
Define and name your own constants
Summations
Complex numbers!

2) Graphing. Capabilities:
Graph up to four equations at once.
Graphs are labeled.
You can drag the graph or pinch to zoom in or out.
Calculator can find roots and intersections.
Can graph in polar coordinates.
Can graph parametric equations.
Can graph parametric equations.
Can graph implicit functions, such as x^2+y^2-4=0. Most calculator apps can't do this!

3) It can make a table of the values of any function you care to enter. You can choose the starting x value of the table, as well as how much x increases for each successive row.

4) Triangle solver. Enter three sides, two sides and an angle, or two angles and a side, and the solver calculates the rest.

5) Polynomial solvers. Find roots of linear, quadratic, or cubic polynomials.

6) The reference hits the high points of the following subjects:
algebra, calculus, geometry, trigonometry, vectors, vector calculus, and classical mechanics. So if you need a reminder of a trig identity . . . or the quadratic formula . . . or the chain rule from calculus . . . and so on, it's right there for you.

7) A unit converter. Your data are in meters, and you need an answer in feet? No problem! With a tap, you can enter the result of your conversion into the calculator. Currently converts different units of the following: acceleration, angle, area, density, distance, energy, force, mass, power, pressure, speed, temperature, time, and volume. Great for physics problem sets!

8) Constants for scientific calculations -- speed of light, strength of gravity at Earth's surface, etc. etc. etc. Tapping on a constant will insert it into your calculation -- i.e, you don't have to key in the value. Again, great for physics problem sets!

9) Works on both iPhone and iPad.

The range of capabilities here is enormous. Even 5 iPhone screenshots and 5 iPad screenshots don't do it justice.

I'd love to learn about your comments or suggestions. You can write me at jockuxyzsch@gmail.com -- but without the xyz. Thanks!

Very powerful calculator (5 stars)
This app is described as intended for education. It is certainly valuable for this purpose. But it is also useful for technically oriented people who come across equations in a book or paper and want to see how they look. There is a vast array of functions available for setting up equations for graphing, including the ability to create new ones---in effect a simple subroutine call. But anything having so much capability is necessarily compli

Excellent (5 stars)
Very very helpful. For the price this has no one should be complaining because this has features that some $100 calculators don't. Just learn how to use it's features and be thankful.

Steal of an app. Wonderful job (5 stars)
I'm not in any higher level math courses at any university. I'm just a guy who is math oriented that wanted to be able to have quick access to a calculator that can actually do things I can't just do in my head. This covers pretty much everything you would need in the course of everyday life and a lot that you wouldn't. Great organization, great price, and great app. One of the easiest 5's I've ever given.
