Knowing that we can write any complex number using its polar coordinates on that plane: Here sin and cos are basic trigonometric functions. 4.2: Complex Fourier Series - Engineering LibreTexts For AC circuits the values of voltage and current are constantly changing. If the phase angle was 90, the projection on the real axis would be zero, and the imaginary part would be equal to the magnitude. The formulas which transform complex numbers from Cartesian form to polar form are exactly the same as classical coordinate transformations: where z|z|z is the modulus/absolute value of the complex number, \varphi is known as an argument or phase (sometimes we use notation arg(z)=\mathrm{arg}(z) = \varphiarg(z)=), and tan\tantan is the tangent of the given argument. The logarithm of a complex numbers (also known as the complex logarithm) can be worked out the following way: One critical remark: since the phases 1\varphi_11 and 1+2k\varphi_1+2k\pi1+2k are equivalent, the complex logarithm has an infinite number of solutions, and we can write the general result as: ln(z1)+i(1+2k)\ln(|z_1|) + i(\varphi_1+2k\pi)ln(z1)+i(1+2k). Where Re (A + B) = x + m is part of the sum of real numbers, And Im(A + B) = y + n is part of sum of imaginary number.
