WitrynaBoth answers (+0.5j and -0.5j) are correct, since they are complex conjugates-- i.e. the real part is identical, and the imaginary part is sign-flipped.Looking at the code makes the behavior clear - the imaginary part of the result always has the same sign as the imaginary part of the input, as seen in lines 790 and 793:. r.imag = copysign(d, … WitrynaIt turns out that square roots of complex numbers are always other complex numbers. Consider 2 + 3 i for the moment. We can square that number: ( 2 + 3 i) 2 = ( 2 + 3 i) ( 2 + 3 i) = 4 + 6 i + 6 i + 9 i 2 = 4 + 12 i − 9 = − 5 + 12 i. Therefore, the square root of − 5 + 12 i is 2 + 3 i. So now we have demonstrated one case where the square ... inches in to pixelsWitrynaComplex numbers have the form a + bi, where a and b are real numbers and i is the square root of −1. All real numbers can be written as complex numbers by setting b = 0. Imaginary numbers have the form bi and can also be written as complex numbers by setting a = 0.
