abstract algebra - Prove that 1+1=2 - Mathematics Stack Exchange Possible Duplicate: How do I convince someone that $1+1=2$ may not necessarily be true? I once read that some mathematicians provided a very length proof of $1+1=2$ Can you think of some way to
If $A A^{-1} = I$, does that automatically imply $A^{-1} A = I$? 1 Short Answer Yes AA -1 = A -1 A = I when the Det (A) ≠ ≠ 0 and A is a square matrix Long Answer A matrix is basically a linear transformation applied to some space For the sake of simplicity I will assume that we are in a 2D plane having 2 basis vectors i ^ and j ^ each having the magnitude of 1 with coordinates (1,0) and (0,1
What is the value of $1^i$? - Mathematics Stack Exchange The formal moral of that example is that the value of 1i 1 i depends on the branch of the complex logarithm that you use to compute the power You may already know that 1 =e0+2kiπ 1 = e 0 + 2 k i π for every integer k k, so there are many possible choices for log(1) log (1)
False Proof of 1=-1 - Mathematics Stack Exchange Oh, it sounds like Ivm asking those questions rhetorically I'm not They are very subtle and difficult questions Ponder them and think about them Part of the problem is that we really abuse what a−−√ a means What does it mean? how many values does it have? Is it unambiguous in meaning?
What does $QAQ^{-1}$ actually mean? - Mathematics Stack Exchange I'm self-learning Linear Algebra and have been trying to take a geometric approach to understand what matrices mean visually I've noticed this matrix product pop up repeatedly and can't seem to de
