Definition
The degree of an algebraic curve is defined as the highest degree of the polynomial equations defining it.
Examples
Linear Curve
The Equation of Straight Line in Plane in Slope-Intercept Form:
- $y = m x + c$
is an example of an algebraic curve which has degree $1$.
Example: $y^2 = 2 x$
The algebraic curve defined by the equation:
- $y^2 = 2 x$
is an example of an algebraic curve which has degree $2$.
That is, it is a quadratic curve.
Example: $x y = 4$
The algebraic curve defined by the equation:
- $y^2 = 2 x$
is an example of an algebraic curve which has degree $2$.
That is, it is a quadratic curve.
