Equations Inequalities System of Equations System of Inequalities Polynomials Rationales Coordinate Geometry Complex Numbers Polar/Cartesian Functions Arithmetic & … There are two main forms of complex number –Cartesian form and polar form . Cartesian complex numbers There are several applications of complex numbers in science and engineering, in particular in electrical alternating current theory and in mechanical vector analysis. When the original complex numbers are in Cartesian form, it's usually worth translating into polar form, then performing the multiplication or division (especially in the case of the latter). The other way complex numbers can be written is in polar form, which are made up of two parts, the modulus and argument. A complex number is a number of the form a + bi, where a and b are real numbers, and i is an indeterminate satisfying i 2 = −1.For example, 2 + 3i is a complex number. (As and ).

The general form of Cartesian representationof a complex number is: which is equivalent with: The Cartesian representation of the z1 and z2complex numbers is: Using Cartesian representation we can plot a complex number in a 2-D plane, having the real part as the x-axis coordinate and the imaginary part as the y-axis coordinate. The x is the real number of the expression and the y represents the imaginary number … a. Division of complex numbers can be done with the help of the denominators conjugate: = ((a + j b) / (c + j d)) ((c - j d) / (c - j d)), = (a c + j a d + j b c + j2 b d) / (c2 + d2) (10). {\displaystyle a} is the real component, … The right hand part of that equation, x + yi, is called the Cartesian form. Retrieved January 12, 2020 from: https://home.cc.umanitoba.ca/~thomas/Courses/ComplexRSDT.pdf. But complex numbers, just like vectors, can also be expressed in polar coordinate form, r ∠ θ .

The x is the real number of the expression and the y represents the imaginary number of the expression. (This is spoken as “r at angle θ ”.) A complex number on the polar form can be expressed as, Z = r (cosθ + j sinθ) (3), r = modulus (or magnitude) of Z - and is written as "mod Z" or |Z|, θ = argument (or amplitude) of Z - and is written as "arg Z", r can be determined using Pythagoras' theorem, r = (a2 + b2)1/2 (4), θ = tan-1(b / a) (5). Any complex number or function can be written in Cartesian form, (1) where is the real part of and is the imaginary part of , often denoted and , respectively.

If you were to represent a complex number according to its Cartesian Coordinates, it would be in the form: (a, b); where a, the real part, lies along the x axis and the imaginary part, b, along the y axis. Complex numbers. The complex conjugate of (a + jb) is (a - jb). A complex number consists of a real part and an imaginary part and can be expressed on the Cartesian form as Z = a + j b (1) where Z = complex number a = real part j b = imaginary part (it is common to use i instead of j) A complex number can be represented in a Cartesian axis diagram with an real and an imaginary axis - also called the Arganddiagram: Addition and subtraction of polar forms amounts to converting to Cartesian form, performing the arithmetic operation, and converting back to polar form. To multiply complex numbers: Each part of the first complex number gets multiplied by each part of the second complex numberJust use \"FOIL\", which stands for \"Firsts, Outers, Inners, Lasts\" (see Binomial Multiplication for more details):Like this:Here is another example: The "modulus" can be calculated by using eq.
