It’s a simple and fun game. All you have to do is drag the given country with into it’s position on the map. Sound easy right? But how high can you score?

It will help you know Europe like your palm. Believe me.

Future versions will have more and more maps. Be prepared!

All reported bugs fixed.

All known known bugs are fixed quite a while but I forgot to make any official announcement.
Hope there is no bug left.

For some reasons, the “Comb” bug is still there. Please don’t use the “Comb” function until the next update. Again, it could take a week or so for an update to be approved. I’m terribly sorry.

It has been nearly a week since I uploaded it to the App Store until it’s available. But it’s ready for sell finally!

SciCal Pro 1.0

This is something you can do with the Full version:

Solving quadratic equation.

- Solving quadratic equation:

All you have to do is enter the three coefficient a,b and c and you it will solve any quadratic equation you can think of. You can also use it to factor any quadratic expression. Just use this formula here: ax^2 + bx + c = (x – x1)(x – x2). (x1 and x2 is 2 solutions of the equation)

Solving system of linear equations.

Solving system of linear equations.

With this feature you can also find the intercept point of any 2 lines in an 2d plane.

I’m trying to add another feature which can solve system of equations of three variables.

a1*x+b1*y+c1*z = d1

a2*x+b2*y+c2*z = d2

a3*x+b3*y+c3*z = d3

It will be available soon!

Integral Screenshot

Yes! It can find the value of any kind of definite integral! (Caution: this is the approximate value!)

Beware that the more complicated the expression is, the more time it takes. Sometime the application may crash if the device has low memory. All you have to do is restart the application. (or the iPhone/iPod Touch in worst case)

But this is useful enough to check the answer of your integration!

In the near future it can do something like this:

Example

I’m working on it. (The application in the example is not mine)

Please let me know if the application has any this part that disappoint you

SciCal Pro

About SciCal:

- SciCal is a virtual scientific calculator application which uses “text input” technology similar to TI or Casio FX calculators. SciCal also takes advantage of many other common functions that are not available on most calculators
- Multiline navigation helps you check and reuse your old expression.
- SciCal has extremely friendly user interface that target both scientific and casual user.
- SciCal also has build-in decimal-fraction converter, units converter, equations solver and integral calculator, all are extremely simple to use.
- This detail and friendly documentation explains every thing you need to know about the functions within SciCal.

SciCal's Main tab.

Functionality:

Edition/Navigation:
[Clear]: Clear the current expression.
[Del] : Delete the next right term of the cursor.
[Home]: Bring cursor to the beginning of current expression.
[End] : Bring cursor to the end of current editing expression.
[<-][->] : Move cursor left or right along the current editing expression.
[^][v] : Navigate along calculated expressions.
Touch : The display space is also a navigation touch-pad.
+ Flick up/down : Navigate along calculated expressions.
+ Short left/right flick : Move cursor left or right along the current editing expression.
+ Long left/right flick : Change keypad.

[Main] tab:
- Contain all number and basic operator button like “+”, “-”, etc. and all basic editing/navigating button.
- To input an expression, simply input the way you write it, then press [=] to get the answer. Ex: to calculate 3 + 4 * (3 – 2) , press [3], [+], [4], [*], [(], [3], [-], [2], [)]
Tip: If you miss any right-parenthesis, the program automatically completes it for you.
You can use the sign “-” for both subtraction and negative number. Ex: “6*-6″ will give the result of “-36″.

[^] : Syntax: x^y = x. Raise x to the y-th power.
[sqrt] : Syntax: sqrt(x). Take square root of x.
Ans] : Return the last answer you got from the last expression calculated.
Tip: If you type in some unfinished expression, for example: “*3″, the program will automatically fill it with Ans.
*3 -> Ans*3
[,] : Used for multi-variable function.

SciCal's Funct tab.

[Funct] tab:
- Provide all lot of commonly use function for all kind of math. Also have basic editing/navigation button.

[sin],[cos],[tan],[csc],[sec],[tan]: Syntax: “sin x” or “sin(x)”. Return the sin/cos/tan/csc/sec/tan value of an angle measuring in radian.
[arc] : Syntax: “arcsin x” or “arcsin(x)”. Combine with [sin],[cos],[tan],[csc],[sec],[tan] to calculate the arcsin,arccos, etc. of an angle measuring in radian. Syntax: [arc]+[sin]+ x or [arc]+[sin] + [{] + x.
[h] : Syntax: “sinh(x)” or “arcsinh(x)”. Combine with [sin], [cos], [tan] or [arc] to calculate sinh, cosh, tanh or arcsinh, arccosh, arctanh of an angle measuring in radian.
[root] : Syntax: “root(x,y)”. Return the value of the x-th root of y.
[logx] : Syntax: “log(x,y)”. Return the value of the logarithm base x of y.
[fact] : Syntax: “fact(x)”. Return the value of the factorial of x.
[ln] : Syntax: “ln(x)”. Return the value of the natural logarithm of x.
[perm] : Syntax: “perm(x,y)”. Return the number of permutation, P(x,y), x<=y.
[comb]: Syntax: “comb(x,y)”. Return the number of combination, C(x,y), x<=y.
[abs] : Syntax: “abs(x)”. Return the absolute value of x.
[log] : Syntax: “log(x)”. Return the logarithm base 10 of x.
[->Frac]: Activate/Deactivate function mode.
[Degree/Radian]: Switch to using degree or radian for trigonometry functions.

SciCal's Const tab.

[Const] tab:
-Provides basic constant and instant-unit-converter-constant
[Pi] : 3.14159265358979323846…
[e] : 2.71828182845904523536…

[X] : Use to create functions for calculating integrals.
- All the instant-unit-converter-constant can be used directly.
Ex: 10km->mi = 6.213 (mi)
(5mi->km)^2= 9.652 (mi square)
[FToC] and [CToF]: Convert from degree Fahrenheit to degree Celsius and vice versa.
[dg->rd] and [rd->dg]:Convert from degree to Radian and vice versa.

Some people say it have ugly interface. Well, I agree, but I think it’s more like simple than ugly . I’ll improve the interface soon. I promise.
