  • Slope Field
    A grid of short line segments on a coordinate plane, each segment's tilt determined by plugging coordinates into a differential equation.
  • Direction Field
    A graphical representation identical to a slope field, showing possible solution directions for a first-order differential equation.
  • First-Order Differential Equation
    An equation involving the first derivative of a function, often written as y' equals a function of x and y.
  • Derivative
    A value indicating the instantaneous rate of change or slope of a function at a specific point.
  • Line Segment
    A short, straight mark drawn at a point on a slope field, its angle determined by the differential equation.
  • Coordinate System
    A grid of x and y values where slope fields are constructed and analyzed.
  • Pattern
    A recurring arrangement of slopes in a field, revealing the general behavior of solutions.
  • Particular Solution
    A unique curve traced through a given point on a slope field, following the indicated slopes.
  • Initial Condition
    A specific point through which a solution curve must pass, used to determine a particular solution.
  • Slant Asymptote
    A line that a solution curve approaches but never touches, often visible in the long-term behavior on a slope field.
  • Zero Slope
    A horizontal line segment in a slope field, occurring where the derivative evaluates to zero.
  • Positive Slope
    A line segment tilting upward from left to right, indicating increasing solutions in a slope field.
  • Negative Slope
    A line segment tilting downward from left to right, indicating decreasing solutions in a slope field.
  • Solution Curve
    A path traced through a slope field, following the direction of each segment, representing a possible solution.
  • Visualization
    A graphical method for understanding the behavior of differential equations without explicit solutions.
