Online Graphing Calculator in Degrees

Reviewed by Calculator Editorial Team

This online graphing calculator allows you to plot mathematical functions using degree-based angles. Whether you're studying trigonometry, analyzing data, or solving real-world problems, this tool helps visualize your equations with precision.

What is a Graphing Calculator in Degrees?

A graphing calculator in degrees is a digital tool that plots mathematical functions using degree-based angles. Unlike radians, degrees provide a more intuitive way to work with angles in common applications such as navigation, engineering, and physics.

This calculator supports standard trigonometric functions (sine, cosine, tangent), polynomial equations, and more. The degree mode ensures all angle calculations are performed using degrees rather than radians.

Note: When using trigonometric functions, ensure your calculator is set to degree mode to avoid incorrect results.

How to Use This Calculator

Using the graphing calculator is straightforward:

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

The calculator will display the graph of your function within the specified range, with degree-based angles used for trigonometric calculations.

Common Functions in Degrees

Here are some common functions you can plot using this calculator:

  • Linear functions: y = mx + b
  • Quadratic functions: y = ax² + bx + c
  • Trigonometric functions: sin(x), cos(x), tan(x)
  • Exponential functions: y = a^x
  • Logarithmic functions: y = log(x)

Each function is evaluated using degree-based angles when applicable.

Worked Examples

Example 1: Plotting a Sine Function

To plot sin(x) from 0 to 360 degrees:

  1. Enter "sin(x)" in the function field.
  2. Set the x-axis range from 0 to 360.
  3. Click "Calculate".

The graph will show the sine wave oscillating between -1 and 1 over the 360-degree range.

Example 2: Quadratic Function

To plot y = x² - 4x + 3 from -5 to 5:

  1. Enter "x^2 - 4x + 3" in the function field.
  2. Set the x-axis range from -5 to 5.
  3. Click "Calculate".

The graph will display a parabola opening upwards with its vertex at x = 2.

Frequently Asked Questions

Can I plot multiple functions at once?
Currently, this calculator supports plotting one function at a time. For multiple functions, you'll need to plot them separately.
How do I convert between degrees and radians?
To convert degrees to radians, multiply by π/180. To convert radians to degrees, multiply by 180/π.
What if my function doesn't plot correctly?
Check your function syntax and ensure you're using the correct mathematical operators. For complex functions, try simplifying or breaking it into smaller parts.
