Plotting Functions
A graphing calculator visualizes how a function behaves across a range of x values. It's essential for understanding algebra, calculus, and trigonometry.
Guide
How it works
Enter any mathematical function using x as the variable. Move your mouse over the graph to see coordinates. Add multiple functions to compare them.
Syntax: use * for multiplication, ^ for powers, sin/cos/tan for trig, sqrt() for square root, π for pi.
How do I enter a function?expand_more
Type the formula using x as the variable. Examples: x^2, sin(x), 2*x+1, sqrt(x). Use * for multiplication.
Can I plot multiple functions?expand_more
Yes — click '+ Add' to add more functions. Each gets a different color so you can compare them.
How do I zoom in?expand_more
Use the Zoom In/Out buttons, or manually change the X min/max and Y min/max values to set your view range.
