THANK YOU!
The tutorial consists of more than 200 live examples from 50 sections. Each of the examples can be copied and run on your own environment. In addition, mXparser provides an extensive collection of over 500 built-in math functions, expressions and symbols. Familiarize yourself with the scope and the syntax. Live testing is the best way to learn. Good luck! 🙂

Below is the code for JAVA, the code for C# is almost identical. To copy the code, double-click inside the frame.
Case 1: Solve 2x-4 = 0 for x in [0, 10]
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("solve( 2*x - 4, x, 0, 10 )");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );
[mXparser-v.5.2.1] Res: solve( 2*x - 4, x, 0, 10 ) = 2.0
Case 2: Solve cos(x) = 0 for x in [0, pi]
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("solve( cos(x), x, 0, pi )");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );
[mXparser-v.5.2.1] Res: solve( cos(x), x, 0, pi ) = 1.57079633
Case 3: Solve cos(x) = 0 for x in [pi, pi] (root not bracketed)
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("solve( cos(x), x, -pi, pi )");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );
[mXparser-v.5.2.1] Res: solve( cos(x), x, -pi, pi ) = -1.57079633
Case 4: Solve x-y = 0 for x in [0, 10] and y = 4
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Argument y = new Argument("y = 4");
Expression e = new Expression("solve( x-y, x, 0, 10 )", y);
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );
[mXparser-v.5.2.1] Res: solve( x-y, x, 0, 10 ) = 4.0
Case 5: Solve sin'(x) = 0 for x in [0, pi]
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Argument x = new Argument("x");
Expression e = new Expression("solve( der( sin(x), x ), x, 0, pi )", x);
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );
[mXparser-v.5.2.1] Res: solve( der( sin(x), x ), x, 0, pi ) = 1.57079633
