The Full (Pro) version is finally out.
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 
Would you let me know if you have any plan to incorporate matrix computation? I need them so much.!
I’m sorry I don’t have any plan to do the matrix computation now even thought it is possible.
Does the Pro version save the current calculation data between usage sessions? Also does it support the V3 iPhone copy & paste functions?
If not are these features that you will be implementing in the not too distant future?
I use the lite version and functionally find it a very good though not as pretty as some other iPhone calculator apps or as convenient to use given the lack of persistence with prior calculations.
It doesn’t have these feature and I’m afraid there will be no update in near future because I’m kinda stop supporting this project to do something else on a bigger scale.
Disappointing but I understand the dilemma. Pity though for as far as I am aware Sci Calc is the only iPhone calculator that comes close to emulating the Casio FX calculators functionality. And the Casio FX calculators are way the best general purpose hand held calculators out there. I suppose I can only hope your bigger project is maybe a full FX emulation. That would be a product worth paying a premium for.
