Graphing Calculator FAQ
Everything you need to know about plotting functions, syntax, and using this online math tool effectively.
Simply type your mathematical equation in terms of ‘x’ (e.g., x^2, sin(x), or 2*x + 3) into the equation field. Adjust the X and Y axis ranges if needed, and the graph will update instantly to visualize your function.
This calculator supports basic arithmetic (+, -, *, /, ^), trigonometric functions (sin, cos, tan), square roots (sqrt), absolute values (abs), logarithms (log), and constants like pi. Use standard JavaScript math syntax.
Currently, this tool plots one equation at a time for clarity and performance. To compare functions, you can change the equation in the input field and observe how the graph updates in real-time.
