  • Vector
    A quantity with both magnitude and orientation, often represented as an arrow in coordinate space.
  • Direction
    The angle measured from the positive x-axis to a vector, indicating its orientation in space.
  • Magnitude
    The length or size of a vector, calculated using its components and representing its strength.
  • X-axis
    The horizontal reference line in a coordinate system, used to measure angles and vector components.
  • Y-axis
    The vertical reference line in a coordinate system, used to measure angles and vector components.
  • Component
    A part of a vector along a specific axis, found using trigonometric functions and the vector's direction.
  • Tangent Function
    A trigonometric ratio comparing the y-component to the x-component, used to determine vector angles.
  • Inverse Tangent
    A function that finds the angle whose tangent is a given value, essential for calculating vector direction.
  • Cosine Function
    A trigonometric ratio used to find the x-component of a vector from its magnitude and direction.
  • Sine Function
    A trigonometric ratio used to find the y-component of a vector from its magnitude and direction.
  • Quadrant
    One of four regions in the coordinate plane, affecting how vector direction is expressed and calculated.
  • Unit Circle
    A circle with radius one, used to relate angles in radians to trigonometric values for vector calculations.
  • Radians
    A unit for measuring angles, often used in trigonometric calculations for vector direction and components.
  • SOHCAHTOA
    A mnemonic for remembering trigonometric ratios, crucial for solving vector component and direction problems.
  • Hypotenuse
    The longest side of a right triangle, corresponding to the magnitude of a vector in component calculations.
