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
