Thanks to people who translate Calculator++ in different languages:\n
Italian - Gabriele Ravanetti\n
Spanish - Jordi Luna\n\n
This application uses next open source libraries:\n
2. Support for differentiation, integration, calculation of sum and product.\n
Examples:\n
∂(cos(t),t)=-sin(t)\n
2∂(tcos(t),t,2)=-4.469\n
Σ(n/n!,n,1,20)=2.7182\n
∫(1/x, x)=ln(x)\n
∫ab(x, x, 0, 10)=50.0
