Calcolatrice scientifica con il plotter. Può risolvere sistemi di equazioni non lineari

Scientific calculator with plotter and solver for systems of non-linear equations. Features:

- Evaluation of expressions. for example:

(6+7)*1.5^(2+0.4)

- Variables. You can create and assign variables

x=6

y=7

z=(x+y)*1.5^(x/3+0.4)

- Solving equations by RKM method.

To solve system of equations for n variables (first need to declare this variables. current values of variables will taken as first approach.):

solve(var1,var2,...,varn)

example:

x=1

y=1

2*x+3*y-12=0

x^2*y=20

solve(x,y)

Result: {3,3909063; 1.739358}
