WitrynaRemember the definition of the imaginary number. i=sqrt (-1) i 2=-1 sqrt (-1)*sqrt (-1) = -1. If you multiply the vector by i twice then you have the same result as multiplying by -1, but there were two operations. If multiplying by i causes a 90 degree rotation then multiplying by i*i causes a 180 degree rotation. WitrynaYes, you can actually create geometric spaces in which angles can be imaginary and even complex. The trick is to note that the most general definition of angle is staged within the framework of inner product spaces: vector spaces which have an operation called the "inner product" that in effect defines how a "dot product" works for that type …
