  • Polar Form

    A representation of a complex number using a distance from the origin and an angle with the real axis.
  • Rectangular Form

    A representation of a complex number as the sum of a real part and an imaginary part, written as x + yi.
  • Modulus

    The distance from the origin to the point representing a complex number in the complex plane.
  • Argument

    The angle measured from the positive real axis to the line representing a complex number in the complex plane.
  • Real Part

    The horizontal component of a complex number, corresponding to its projection on the real axis.
  • Imaginary Part

    The vertical component of a complex number, corresponding to its projection on the imaginary axis.
  • Pythagorean Theorem

    A formula used to calculate the modulus of a complex number by taking the square root of the sum of the squares of its real and imaginary parts.
  • Inverse Tangent

    A function used to determine the argument of a complex number from the ratio of its imaginary and real parts.
  • Quadrant

    One of four regions in the complex plane, each affecting the calculation of the argument for a complex number.
  • Unit Circle

    A circle of radius one centered at the origin, used to find exact values for trigonometric functions during conversions.
  • Cosine

    A trigonometric function used to determine the real part of a complex number in polar form.
  • Sine

    A trigonometric function used to determine the imaginary part of a complex number in polar form.
  • Distribution

    The process of multiplying the modulus by the cosine and sine components to convert from polar to rectangular form.
  • Degree Mode

    A calculator setting that interprets angles in degrees, important for correct argument calculations.
  • Radian

    A unit of angular measure used in trigonometric calculations, often appearing in polar form expressions.
