What is a Graphing Calculator?
A graphing calculator is a tool that plots mathematical equations on a coordinate plane. It converts algebraic expressions into visual representations, making it easier to understand function behavior, identify key features like intercepts and extrema, and solve equations graphically.
A graphing calculator plots mathematical functions visually to help you understand their behavior. Use our free online grapher to visualize any function like y = x^2, y = sin(x), or y = e^x. You can plot multiple functions, zoom in/out, find zeros, maxima, minima, and intersection points.
Key Features
- •Plot up to 10 functions simultaneously with different colors
- •Use standard math notation: x^2, sqrt(x), sin(x), log(x), e^x
- •Interactive pan and zoom to explore any region of the graph
- •Find zeros (x-intercepts) where the function crosses the x-axis
- •Find local maxima and minima (turning points)
- •Find intersection points between two functions
- •Supports trigonometric, exponential, logarithmic, and polynomial functions
- •Export graphs as images for reports and presentations
