Properties of dictionary order topology Choose the correct option My attempt : According to Munkres the order topology on $\mathbb{R} \times \mathbb{R}$ h...

It seems the definition of a parallelogram is locked to quadrilaterals for some reason. Is there a reason for this? Why couldn't a parallelogram (giv...

How can I show that $(A^T)^+=(A^+)^T$, where $A^+$ is Moore-Penrose Inverse? I know there are 4 properties of the Moore-Penrose Generalized inverse, for e...

I've seen this question somewhere and I've been thinking about it a lot but couldnt think of an answer. Say you have oracles A and B for the TQF...

I do not understand why functions are needed in mathematics(algebra, to be exact). They are nearly the same as regular equations. Yeah, "there should be o...

I tried doing this by putting $$\frac{ \sin p}{\sqrt2} +\frac{ \cos p}{\sqrt2} = 0 $$ which implies $$ \sin(p + π/4) = \sin 0 $$ which implies $p+ π/4 = n...

Let A and B be events. It seems to make sense to be that the probability that A occurs is equal to the probability that A and B both occur PLUS the probab...

I have been reading and watching videos about local and global extrema, but all of this material covers the topic just graphically, and nobody really expl...

Suppose that we have a formula like $y=\frac{1}{\sqrt{x}}$. Is it correct to say that y is inversely proportional to x? what about y is inversely related ...

This is a problem from Discrete Mathematics and its Applications: Explain why $A \times B \times C$ and $(A \times B) \times C$ are not the same. I unders...
