COMPLEX (real_num, i_num, [suffix]) The COMPLEX function syntax has the following arguments: Real_num Required. If omitted, suffix is assumed to be "i". The lengths of the real and imaginary projections are related to the magnitude of the vector cosine and sine of the phase angle respectively. I will spare you the math, but the resulting power waveform is also a sinusoid (red trace), but with twice the frequency and offset above zero. From the source of Varsity Tutors: Complex Numbers, complex plane, purely imaginary, imaginary unit, Cartesian Plane. Complex Number extends the concept of one-dimensional line to a two-dimensional complex plane and uses the horizontal axis for the real part . This app never disappointed me, i bet a lot of coding went into this app and as a fellow coder id love to see all the code. We call this a vector quantity, and traditionally use bold font to distinguish them from magnitude only (or scalar) quantities. This time the power is positive in the first and third quarter-cycles, when the capacitor is charging, and negative in the second and fourth quarter-cycles when the capacitor is discharging. Most loads in AC systems will have some resistive and some reactive component, so one number is not enough to describe power in these cases. Fast and easy to navigate, gets straight to the point and in a way helps you figure out your own question and then answers it. The imaginary part; im(1+I) Modulus of a complex number; absolute(1+I) The argument; arg(1+I) . You can probably see that if the phase angle is zero, the projection on the real axis is equal to the magnitude and the imaginary part is zero. But other than that it's amazing, sometimes you just have to go to a calculator or google,but I still love it. To calculate the real part of the following complex expression z=`(1+i)/(1-i)`, As an imaginary unit, use i or j (in electrical engineering), which satisfies the basic equation i2 = 1 or j2 = 1.
