The most comprehensive graphing calculator on the web.
π: Ctrl+P or
Alt+P or pi.
∞: Ctrl+8
or Alt+8 or infinity.
θ: Ctrl+T or
Alt+T or theta. You can also use x or t instead of θ in polar mode; the Graphing Calculator replaces them with θ when you press Draw Graph or Enter on the keyboard.
√: Ctrl+2 (also sqrt) for square root.
Γ: Ctrl+g for the Gamma function.
By using your mouse you can do the following
Drag the graphs to view the desired region. Also double-click in the graphing area to move the origin to where you have clicked.
Change the scale on an axis: Hold down Ctrl key and click a point on an axis. That point will be labelled 1 and becomes the new unit and the graphs are re-drawn to reflect the change of scale.
Rotate an axis: Hold down Alt key, click on an axis (the color of the axis changes to red) and drag. The axis will rotate accordingly, and the graphs are re-drawn to reflect the rotation of the axis.
If you click near the origin, all axes will be rotated at the same time.
Instruction
This Online Graphing Calculator automatically detects the type of expressions you type. Type in a Function, Equation, Parametric Curve or Point Set in any input box on the left of the Graphing Calculator and press Graph or tap Enter.
Syntax by examples:
Function: f(x) = 2xsin(πx) intvl=(-∞, ∞)
You don't have to type the intvl=(); the calculator appends it automatically when you press Graph. You can then change the end points.
Equation: 3x^2y^3 = 2xsin(πx)
You don't have to type the intvl=(); the calculator appends it automatically when you press Graph. You can then change the end points.
Polar Graphing Calculator: select Polar on the coordinate plane to graph using polar coordinate system.
Equation Solver: Press f(x) = 0 and the Graphing Calculator finds x-intercepts of the graph of the function on an interval by solving the equation.
Curve Fitting: When you entered points, press P(x) or L(x) to calculate and graph the polynomial function of the least degree passing through the given set of points or the line that best fits the points according to the Gauss' least-squares criterion.
Derivative Calculator: press f'(x) or p'(x) to calculate derivatives of functions or parametric equations. The Graphing Calculator also graphs the 1st and 2nd derivatives of them.
Press ∫f and the Graphing Calculator finds proper definite integral, area and the arc length of a function.
Press f(...) or p(...) to generate a table of values for functions or parametric equations.
Evaluatefunctions or parametric equations by entering values in the text box provided.
