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!
• Sig figs (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 the roots of a polynomial, up to 10th degree.

7) System of linear equations solver.

8) 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.

9) 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.

10) 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!

11) Statistics mode, including options for scatter plots and for regression lines.

12) Works on both iPhone and iPad.

13) Derivatives! (Answer simplification is limited.)

Graphing Calculator Features:

Graphing: Plot polar, Cartesian, and parametric graphs. There’s no limit to how many expressions you can graph at one time—and you don’t even need to enter expressions in y= form!

Sliders: Adjust values interactively to build intuition, or animate any parameter to visualize its effect on the graph.

Tables: Input and plot data, or create an input-output table for any function.

Statistics: Use regressions to find the lines (or other curves!) that best fit your data.

Zooming: Scale the axes independently or at the same time with the pinch of two fingers, or edit the window size manually to get the perfect view of your graph.

Points of Interest: Touch a curve to show its maximum and minimum values, intercepts, and points of intersection with other curves. Tap any of these points of interest to see their coordinates. Hold and drag along a curve to see the coordinates change under your finger as you trace.

- - -

Scientific Calculator Features:

Variables: Assign values to variables that you can use in other expressions. Since all of your work is held in the expressions list, you can compute a value once and use it in many places simultaneously. Take advantage of the “ans” key, which always stores the value of the previous expression.

Arithmetic: Beyond the four basic operations, the scientific calculator also supports exponentiation, radicals, absolute value, logarithms, rounding, and percentages.

Trigonometry: Evaluate the fundamental trigonometric functions and their inverses using either radians or degrees for angle measure.

Statistics: Compute the mean and standard deviation (sample or population) of a list of data.

Combinatorics: Count combinations and permutations and calculate factorials.

- - -

Four-Function Calculator Features:

Simple and Beautiful: Just the basics done right. Add, subtract, multiply, divide, and take square roots.

Multiple Expressions: Unlike many four-function calculators, all of your previous work remains visible on the screen. The special “ans” key always holds the value of the previous computation (and updates automatically!), so you never have to remember or copy a result.

The perfect tool for students, teachers and engineers, built on an extremely powerful algebra engine, Symbolic Calculator is capable of helping with any kind of math problems ranging from basic arithmetics to university-level advanced math. It offers all the advantages of an advanced graphing/scientific calculator mixed with the convenience of modern mobile apps.

Features overview:

- Exact arithmetic. 5/15 is 1/3 and not 0.333 (unless you select rounded numerical mode)
- Store unlimited number of variables, create custom functions
- Algebra: operations on polynomials, such as expansion and factorization, collecting terms, division with remainder, etc.
- Calculus: derivatives, integrals, limits, taylor expansion, etc.
- Linear algebra: full support for matrix operations and many useful functions such as: determinant, rank, reduced echelon form, characteristic polynomial, etc.
- Solvers: equations or equation systems, symbolically or numerically, differential equations
- Full support for complex arithmetics
- Plotting
- Session management: export, import sessions or create PDF files
- Many other versatile built-in functions with descriptions and examples
