Function Plotter with Derivatives and Integrals

An interactive function plotter that visualizes mathematical functions, their derivatives, and integrals with real-time controls.

Features

• Plot various function types: trigonometric, polynomial, exponential, and custom
• Real-time visualization of derivatives (up to 4th order)
• Integral calculation with area selection
• Interactive controls for function parameters
• Custom equation input with syntax checking
• Responsive design that adapts to screen size

Supported Functions

• Trigonometric: sin, cos, tan with adjustable parameters
• Polynomial: Cubic functions (Ax³ + Bx² + Cx + D)
• Exponential: Ae^(Bx) functions
• Custom: User-defined equations using math.js syntax

Controls

Control	Description
Function Type	Select between trigonometric, polynomial, exponential, or custom functions
Parameters	Adjust function parameters with sliders (amplitude, frequency, etc.)
Derivative	Toggle derivative plot and select derivative level (0th to 4th)
Integral	Activate integral mode and select area to calculate definite integral
Scale	Adjust plot scale manually or reset to default

Custom Equation Syntax

The custom function input supports mathematical expressions using:

• Basic operators: +, -, *, /, ^
• Mathematical functions: sin(x), cos(x), tan(x), exp(x), log(x), etc.
• Constants: pi, e
• Variables: x (independent variable)

Example: 2*sin(3*x) + x^2 - 4
