This time, the real part can be written as Re(A * B) = x * m - y * n, and the imaginary part as Im(A * B) = x * n + y * m. Remember that complex number calculators use a negative sign in the real part because, at some point, we are faced with the product of two numbers i * i, which by definition is -1. Similarly, b is the imaginary part written as Im(z). It is used to solve problems and to understand the world around us. Dividing complex numbers is almost the same with this notation: rewriting the result as: F/G=z1/z2|F / G| = |z_1/z_2|F/G=z1/z2, and arg(F/G)=12\arg(F / G) = \varphi_1\!-\!\varphi_2arg(F/G)=12. Description : Writing z = a + ib where a and b are real is called algebraic form of a complex number z : a is the real part of z; b is the imaginary part of z. As you would expect, the sinusoidal voltage across the resistor (green trace) results in a sinusoidal current with the same phase (blue trace). Of course, the division is possible only if G0G \neq 0G=0. If the first number is A = x + yi and the second number is B = m + ni, then the sum of two complex numbers is: $$ A + B = x + yi + m + ni = (x + m) + (y + n) * I $$. a x+iy = a x [cos (y log a) + i sin (y log a)] 6.
