How many irrational numbers can exist between two rational numbers ? As there are infinite numbers between two rational numbers and also there are infinit...

Saw this in a physics lecture. This all assumes we have some function, $y=f(x)$. First he defined $$ds = \sqrt{dx^2+dy^2},$$ where the professor drew a pi...

I found this problem on a thread on Stack overflow where it was posted as "job interview question". Unfortunately I cannot find the question. But I saved ...

In graph theory, for a connected, undirected finite graph one can easily find a set of fundamental cycles - I understand that part. This forms a basis of ...

I want to know what steps to do the permutation test (and the R/SAS code) for one-way ANOVA? Would you give me the specific steps? Thanks, Buddies!

Why not? I'm trying to design a calculus I problem. I want them to eventually prove that the volume of a cone (oblique or even with irregular base) i...

$ \operatorname{Var}(X) = E[X^2] - (E[X])^2 $ I have seen and understand (mathematically) the proof for this. What I want to understand is: intuitively, w...

Let's say I have a data set:- $${1,2,3,4,5}$$ I decide to find the mode though it would not be an appropriate measure of central tendency. But still....

By definition: If$ \ A$ and $B\ $are sets and every element of$ \ A\ $ is also an element of $ \ B \ $then we can say $ \ A\ $is a subset of $ \ B, \ $and...

The prompt is to find the parabola equation for the main span of Golden Gate bridge. Based on the $3$ points on the parabola: $(0,227)$; vertex $(640,75)$...
