Supported Functions & Equation Types

This calculator supports a wide variety of mathematical expressions:

Linear functions: y = mx + b
Quadratic functions: y = ax² + bx + c
Polynomial functions: y = x³ + 4x² − 2x + 7
Trigonometric: sin(x), cos(x), tan(x), sec(x), etc.
Exponential & Logarithmic: y = eˣ, y = ln(x), y = log(x)
Rational functions: y = (x² + 2) / (x − 3)
Constants & Variables: π, e, or user-defined symbols

Example:

Graph the equation: y = 3x − 2

Solution:

This is a straight-line (linear) function. Sample points:

x = 0 → y = −2 → point (0, −2)
x = 1 → y = 1 → point (1, 1)
x = −1 → y = −5 → point (−1, −5)

Plotting these points results in a straight line rising from bottom-left to top-right.
