use calculation rules for real and complex numbers use basic trigonometric funktions and complex exponential function. Polar coordinates.

( In this unit we look at the polar form of a complex number. You will have already seen that a complex number takes the form z = a + bi. This form is called The quotient of two complex numbers in polar form is the quotient of the two moduli and the difference of the two arguments. Quotients of Complex Numbers in But complex numbers, just like vectors, can also be expressed in polar coordinate form, r ∠ θ . (This is spoken as “r at angle θ ”.) The figure to the right shows an Complex Numbers in Rectangular and Polar Form. To represent complex numbers x + yi geometrically, we use the rectangular coordinate system with the Complex Numbers in Polar Form. Let us represent the complex number where in the complex plane which is a system of rectangular axes, such that the real part is It should be relatively easy to see that, if a complex number z has magnitude r and argument θ, then: z=r(cosθ+isinθ) This is called the polar form of a complex The polar form of a complex number.

### In the case of a complex number, r represents the absolute value or modulus and the angle θ is called the argument of the complex number. This can be summarized as follows: The polar form of a complex number z = a + b i is z = r ( cos θ + i sin θ) , where r = | z | = a 2 + b 2 , a = r cos θ and b = r sin θ , and θ = tan − 1 ( b a) for a > 0 and θ = tan − 1 ( b a) + π or θ = tan − 1 ( b a) + 180 ° for a < 0 .

Example 7 Convert the given complex number in polar form: 1 + i√3. Given z = 1+ √3i Let polar form be z = r (cosθ + i sinθ) From ( 1 ) & ( 2 ) 1 + √3i = r ( cosθ + i sinθ) 1 + √3i = r〖 cos〗θ + 𝑖 r sinθ Adding (3) & (4) 1 + 3 = r2 cos2θ + r2 sin2θ 4 = 𝑟2 cos2θ + r2 sin2θ 4 = 𝑟2 ( cos2θ + sin2θ ) 4 = 𝑟2 × 1 4 Operations with one complex number This calculator extracts the square root , calculate the modulus , finds inverse , finds conjugate and transform complex number to polar form . The calculator will generate a step by step explanation for each operation. Writing a Complex Number in Polar Form Plot in the complex plane.Then write in polar form. Solution The complex number is in rectangular form with and We plot the number by moving two units to the left on the real axis and two units down parallel to the imaginary axis, as shown in Figure 6.43 on the next page.
