  • Trigonometric Equation
    An expression involving trigonometric functions set equal to a value, requiring solutions for angle values that satisfy the equality.
  • Trigonometric Identity
    A universally true relationship between trigonometric functions, used to simplify or transform equations.
  • Pythagorean Identity
    A fundamental relationship connecting the squares of sine, cosine, or tangent functions, often used to rewrite expressions.
  • Double Angle Identity
    A formula expressing a trigonometric function of twice an angle in terms of functions of the original angle.
  • Even-Odd Identity
    A property describing how trigonometric functions behave when their input is negated, distinguishing between even and odd functions.
  • Unit Circle
    A circle of radius one centered at the origin, providing reference values for trigonometric functions at key angles.
  • General Solution
    A formula that includes all possible angle values satisfying a trigonometric equation, often using a periodic term.
