Math Function Plotter GUI

Overview

The Math Function Plotter GUI is a desktop application designed to plot mathematical functions. Built using PySide2 for the GUI and Matplotlib for plotting, this application allows users to input mathematical expressions, specify the range for the x-axis, and view the resulting plot.

Features

• Function Input: Users can enter mathematical functions with support for various operators and functions.
• Range Specification: Define the x-axis range with minimum and maximum values.
• Step Size: Set the interval between plotted points.
• Plotting: Generate and display the graph based on user input.
• Error Handling: Real-time validation of inputs with error messages.
• Instructions: Access detailed instructions on how to use the application.

Supported Mathematical Functions

• Operators: +, -, /, *, ^ (exponentiation)
• Trigonometric Functions: sin(x), cos(x), tan(x), etc.
• Square Root: sqrt(x)
• Logarithms: log(x), log10(x), log2(x)
• Constants: pi, e^x (as exp(x))

Error Messages

The application provides feedback on input errors through visual cues. Below are descriptions of the various error states and corresponding images.

1. Plot Function is an Empty String

• Description: This error occurs when the plot function input field is left empty.

2. Plot Function is Not a Valid Mathematical Function

• Description: This error indicates that the input provided for the plot function is not a valid mathematical expression.

3. X Min is an Empty String

• Description: This error is shown when the minimum x value input field is left empty.

4. X Min is Not a Valid Number

• Description: This error occurs when the minimum x value input is not a valid number.

5. X Max is an Empty String

• Description: This error appears when the maximum x value input field is left empty.

6. X Max is Not a Valid Number

• Description: This error is displayed when the maximum x value input is not a valid number.

7. X Max is Not Greater Than X Min

• Description: This error indicates that the maximum x value is not greater than the minimum x value.

8. Step is an Empty String

• Description: This error is shown when the step size input field is left empty.

9. Step is Not a Valid Number

• Description: This error appears when the step size input is not a valid number.

10. Step is Zero

• Description: This error occurs when the step size is set to zero.

Successful plots:

• f(x) = sin(x)

• f(x) = x^3 + 6*x^2 - 3*x + 6
