CalcPro

<p><br /> This is an engineering calculator, with equation solvers, interpolations, wolfram alpha, converter, complex numbers... and more in the future!</p>
<br />
<p><br /> This is an application designed for engineers but can be used by anyone. Once you open the app you'll see a simple calculator with a swipe keyboard but there's much more behind.</p>
<br />
<p><br /> This is a powerful application which has the following features:</p>
<br />
<p><br /> - Equation Solver: You can solve almost any equation. It supports:<br /><br /> -> Non-linear equations: Any type of equation, such as: 5*x+sin(x^3+2)=8 (up to 10 equations and variables, you can see 2 equations solved in the screenshots)<br /><br /> -> Linear equations: Like 2*x+3*y=8, -3*x+6*y=3 (up to 10)<br /><br /> -> Polynomials: Up to grade 20 (complex and non-complex solutions)</p>
<br />
<p><br /> - Interpolation<br /><br /> -> Simple: Perfect for thermodynamic tables with only one variable (for example Temperature)<br /><br /> -> Double: 2 variables interpolation. See screenshots for a preview<br /><br /> -> Points to line: If you have a set of points (x,y) this tool will find the closest line and will give you the R^2 (Just like Excel).</p>
<br />
<p><br /> - Converter: It's useful to have a converter inside the app. It's got 19 conversions: length, area, volume, angle, time, speed, acceleration, flow, mass, force, torque, energy, density, pressure, dynamic viscosity, kinematic viscosity, temperature and currency.</p>
<br />
<p><br /> - Wolfram Alpha search: Just touch the search button</p>
<br />
<p><br /> - Complex numbers: The calculator supports complex numbers in both rectangular and polar notation. Polar notation us useful for phasors in Circuit Analysis.</p>
<br />
<p><br /> - Variables: Just save any number as a variable and use it later.</p>
<br />
<p><br /> - Constants: 6, more in next updates.</p>
<br />
<p><br /> - Radians/degrees</p>
<br />
<p><br /> - Easier decimal notation: 1.000000 is 1, 99999999 is 9.999E7 (depending of the decimal precision)...</p>
<br />
<p><br /> - And probably more features in the future!</p>
