Description
It is the scientific graphing calculator which can plot 2D and 3D graph. It is similar to Texas Instruments TI83, TI84. It has more features such as plotting 3D graph for mathematics functions.
News: This app supports iPad natively with full width and height.
Features:
 plot 2D and 3D graph
 plot multiple functions on one graph
 any plot function will be saved and can be edited and plotted later.
 send email with the graph after you done.
 easily zoom in and out on the graph
 can operate on very large number mathematics.
 convert number to any base
 compute permutation, combination  compute greatest common denominator
 compute least common multiple of a set of rational numbers
 compute factorial and fibonacci number.
 provide many trigonometric functions
 calculate the norm of value
 provide matrix addition, multiplication
 compute matrix determinant, inverse matrix.
 stream line interface so you can easily change the input with finger.
 copy/paste your result to any other application
 provide many other scientific functions
 buildin Help manual for user.
After you use this graphing calculator, you will never want to use any other graphing calculator. It is very simple and easy to use.
Functions in scientific graphing calculator:
= it can plot f(x), f(x,y)
= The following math functions you can use to plot 2D and 3D Graph:
 abs, norm, rand, acos,
 sin, cos, tan, asin, atan,
 sinh, cosh, tanh, log, ln, exp, sqrt,
 any linear, quadratic or x to n, exponential functions.
= The following math functions you can use for calculation:
 max, min, avg, gcd, root, cot, coth
 asinh, acosh, atanh, base, perm, comb,
 ceil, floor, round, lcm, fib
= The following function use to compute matrix
 determinant: det(x)
 inverse matrix: inverse(x)
To start calculate, simply enter:
7+30*6
Click button "ans". The result will be return to you.
To Plot a linear function, simply enter:
13*x+6
Click "Plot" button. You do not need enter "y=" in the front.
It is wrong if you enter: y=13*x+6 because it assumed it is a function of x or y or both. It is also wrong if you enter 13(x)+6. For example, if you want to plot f(x,y)=3*x+4*y, you only need input the second part. Note that you need math operator for any math formula.

It is highly recommended that you read the "Quick Start Guide" in buildin Help document before use this application.

Extremely Buggy

Not sure how/why Apple let this one through. Unusable, full of bugs.
Does not work as pictured

Nice GUI, only wish the application worked

I like the key layout and general appearance of the interface. It looks like it should work. If I han't read a good review on this I probably never would have tried it. if the designer can just hookedup with someone that knows how to program it would be great! Does not graph circles properly and therefore can not give intersections between parabola's and circles or linear equations. After more than an hour of trying to get it to function resulted in frustration. Not intuitive. Just the entertainment value of trying to get it work was worth the 99 cents to me but I'm easily entertained when it comes to math, programming and that kind of stuff. Tried to plot a simple parabola x^2+12x+36 and got an error on the plot and wouldn't solve the equation. Really?. Also  Select, Select All and the corresponding functions copy, cut paste do not function in the entry area. If you don't like to test stuff out then don't way your dollar.
