Scientific Graphing Calculator
Description
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!
- Sig figs (requires iOS 6; enable under settings)
- Programmable keys (enable under settings)
2) Graphing. Capabilities:
- Graph up to nine 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) Vector and Matrix calculator. Vector dot and cross products. Multiply and add matrices. Determinant, transpose, Eigenvalues and Eigenvectors.
4) 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.
5) Triangle solver. Enter three sides, two sides and an angle, or two angles and a side, and the solver calculates the rest.
6) Polynomial solvers. Find roots of linear, quadratic, or cubic polynomials.
7) 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.
8) 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! You can also define your own units.
9) 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!
10) Works on both iPhone and iPad.
