Free Graphing Calculator in Degrees

How to Use This Graphing Calculator

Our graphing calculator provides a simple interface for plotting functions in degrees. Here's how to use it:

1. Enter your function in the input field (e.g., "sin(x)", "2x^2 + 3x - 5")
2. Set the x-axis range (minimum and maximum values)
3. Click "Calculate" to generate the graph
4. View the result and adjust as needed

The calculator will display the graph with the function plotted over the specified range. You can see the exact points calculated in the data table below the graph.

Formula Used

The graphing calculator evaluates the function you provide at multiple points within the specified x-axis range. The formula for each point is simply:

Where:

• y is the output value
• f(x) is your input function
• x is the input value within the specified range

The calculator uses JavaScript's built-in Math functions to evaluate trigonometric and other mathematical operations. All angles are interpreted in degrees unless specified otherwise.

Worked Examples

Example 1: Plotting a Sine Function

Let's plot the sine function (sin(x)) from 0 to 360 degrees:

1. Enter "sin(x)" in the function field
2. Set x-min to 0 and x-max to 360
3. Click "Calculate"

The graph will show the familiar sine wave pattern, starting at 0, peaking at 1, returning to 0, and reaching -1 before completing the cycle.

Example 2: Quadratic Function

Now let's plot a quadratic function (2x² + 3x - 5) from -5 to 5:

1. Enter "2*x*x + 3*x - 5" in the function field
2. Set x-min to -5 and x-max to 5
3. Click "Calculate"

The graph will show a parabola opening upwards with its vertex near x = -0.75. The y-values will range from approximately -10 to 10 within this range.
