Solve Quadratic Equation for Positive Real Roots
Description
This function solves a quadratic equation of the form 'ax^2 + bx + c = 0' and returns only the positive real roots. It handles complex intermediate calculations and returns real numbers if the roots are real.
Usage
quad(a = 3, b = 2, c = -1)
Arguments
a |
The coefficient of the x^2 term. Can be complex. |
b |
The coefficient of the x term. |
c |
The constant term. |
Value
A numeric vector containing the positive real root(s) of the quadratic equation. Returns 'numeric(0)' if no positive real roots are found. Returns a single value if both positive roots are identical.
Examples
# Example 1: With specific coefficients
quad(a = 1, b = -3, c = 2) # x^2 - 3x + 2 = 0
