  • Polar Form
    A representation using distance from origin and angle with real axis, expressed as r(cos θ + i sin θ).
  • Rectangular Form
    A representation using real and imaginary parts, written as x + yi.
  • Magnitude
    The distance from the origin to the complex number, calculated with the Pythagorean theorem.
  • Argument
    The angle measured from the positive real axis to the complex number, adjusted by quadrant.
  • Quadrant
    One of four regions in the complex plane, determining how the angle is adjusted.
  • Pythagorean Theorem
    A formula used to find the magnitude, combining squares of real and imaginary parts.
  • Inverse Tangent
    A function used to determine the angle from the ratio of imaginary to real parts.
  • Unit Circle
    A circle with radius one, providing known values for sine and cosine to simplify calculations.
  • Cosine
    A trigonometric function used to find the real part when converting from polar to rectangular form.
  • Sine
    A trigonometric function used to find the imaginary part when converting from polar to rectangular form.
  • Real Part
    The horizontal component of a complex number, found using magnitude and cosine of the angle.
  • Imaginary Part
    The vertical component of a complex number, found using magnitude and sine of the angle.
  • Degree Mode
    A calculator setting for measuring angles in degrees, important for correct angle calculation.
  • Radian
    A unit for measuring angles, often used in trigonometric calculations and unit circle values.
  • Distribution
    A process of multiplying the magnitude into cosine and sine components to convert forms.
