Building Functions
📈 Online graphing of functions
Our tool allows you to instantly visualize mathematical formulas. It plots both simple linear functions and complex trigonometric or logarithmic equations. Supports scaling and working with multiple functions simultaneously.
x^2 - 4) and click “Build”. The system will select the scale itself. 📚 Syntax cheat sheet
To make the graph correctly, use the correct notation:
| Operation | How to write | Example |
|---|---|---|
| Addition / Subtraction | + and - | x+5 |
| Multiplication | * (required!) | 2*x (not 2x) |
| Degree | ^ or ** | x^2 |
| Root | sqrt(x) | sqrt(x+4) |
| Trigonometry | sin, cos, tan | sin(2*x) |
| Logarithm / Modulus | log, ln, abs | ln(x) |
What is this calculator used for?
- Homework check:Make sure you have correctly found the intersection points with the axes or the vertices of the parabola.
- Function research:The areas of increasing, decreasing and breaking points are clearly visible.
- Preparing for the Unified State Exam: Practice visualizing the behavior of functions (parameters, modules), which is useful for problems with parameters.
Frequently asked questions (FAQ)
❓ Why is the graph empty or a line is displayed?
Most often the error is in the syntax. Check:
1. Did you put the multiplication sign? (you need to write 2*x, not 2x).
2. Is the scale too big? Try changing the axis ranges to standard (-10 to 10).
❓ How to build several graphs at once?
In the current version, you can enter functions one by one or use the “Add function” button (if it is active in the interface). To compare two graphs, it is convenient to open the site in two adjacent tabs.
❓ What do “sqrt” and “pow” mean?
This is programming notation adopted in all online calculators. Sqrt (Square Root) is the square root. Pow (Power) or the ^ icon is an exponentiation.
