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

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)
Why is $1^{\\infty}$ considered to be an indeterminate form The reason why 1∞ 1 ∞ is indeterminate, is because what it really means intuitively is an approximation of the type (∼ 1)largenumber (∼ 1) l a r g e n u m b e r And while 1 1 to a large power is 1, a number very close to 1 to a large power can be anything
