Nettet25. okt. 2024 · They may seem strange at first, but we quickly find that we can add, subtract, multiply and divide complex numbers just as we do with real numbers. To add and subtract complex numbers, you just combine the real parts and the imaginary parts, like this: (5 + 3 i) + (2 + 8 i) = (5 + 2) + (3 + 8) i = 7 + 11 i. This is similar to combining … Nettet27. mar. 2010 · Now the limit of the function at a point could be imaginary, because the function value could get arbitrarily close to an imaginary number. So there's no great mystery about limits being complex or imaginary; if the function value can take on those values, then limits can be of those values.
