  • Inverse Trigonometric Function
    A mathematical tool that retrieves an angle from a given trigonometric value, always within a specific interval.
  • Inverse Sine
    A function returning an angle between -π/2 and π/2 whose sine equals a given value between -1 and 1.
  • Inverse Cosine
    A function yielding an angle between 0 and π whose cosine matches a given value from -1 to 1.
  • Inverse Tangent
    A function producing an angle between -π/2 and π/2 whose tangent equals any real number.
  • Unit Circle
    A circle of radius one centered at the origin, used to relate angles to trigonometric values.
  • Specified Interval
    A restricted range of angles where an inverse trigonometric function provides valid outputs.
  • Composite Function
    An expression where one function is nested inside another, requiring inside-out evaluation.
  • Vertical Line Test
    A graphical method to determine if a curve represents a function by checking if any vertical line crosses it more than once.
  • One-to-One Function
    A function where each output is paired with exactly one input, ensuring an inverse exists.
  • Undefined Value
    A result that cannot be computed because the input falls outside the function's domain.
  • Principal Value
    The unique angle returned by an inverse trigonometric function, always within its specified interval.
  • Reflection over y = x
    A transformation used to derive the graph of an inverse function by swapping x and y coordinates.
  • Quadrant
    A section of the coordinate plane, used to identify where angles and their trigonometric values lie.
  • Radian Mode
    A calculator setting where angles are measured in radians, commonly used for trigonometric calculations.
  • Domain
    The set of all possible input values for which a function is defined and produces real outputs.
