WebExample: the number 3 + 4i To turn 3 + 4i into reix form we do a Cartesian to Polar conversion: r = √ (3 2 + 4 2) = √ (9+16) = √25 = 5 x = tan -1 ( 4 / 3 ) = 0.927 (to 3 decimals) So 3 + 4i can also be 5e0.927 i It is Another Form It is basically another way of having a complex number. WebA General Note: Imaginary and Complex Numbers. A complex number is a number of the form a+bi a + b i where. a a is the real part of the complex number. bi b i is the imaginary part of the complex number. If b = 0 b = 0, then a+bi a + b i is a real number. If a =0 a = 0 and b b is not equal to 0, the complex number is called an imaginary number.
