\iint_{R} \frac{x - y}{x + y + 1}

https://math.stackexchange.com/questions/652711/let-r-be-the-square-with-vertices-0-0-1-1-2-0-1-1-evaluate-ii

The region of integration and the form of the integrand is practically begging to be transformed via a rotation by

π / 4

u = x - y, v = x + y,

which then turns the region of ...

Basis for an invertible linear transformation

https://math.stackexchange.com/questions/124370/basis-for-an-invertible-linear-transformation

If your coordinate vectors are row vectors, then

[T]_{B}

is correct. Otherwise, it should be transposed. I will continue to work in the world of row vectors (assuming your first matrix is ...

How to Tell if these vectors linearly independent

https://math.stackexchange.com/questions/2473693/how-to-tell-if-these-vectors-linearly-independent

Suppose you put them in a matrix,

A = [v_{1} v_{2} v_{3}]

and reduce them to row echelon form. As we can see from the matrix that it has

3

pivot columns, i.e., it is full ...

In how many ways can I split a binary number of length

n

m

parts such that no part starts with 0?

https://math.stackexchange.com/q/1974232

The first digit of each of the

m

parts must be one of the

1

s in the given number, where it is fixed that the first part starts with the first

1

k

, then there are

(m - 1 k - 1)

How can the probability that a number contains the digit 3 be 1?

https://math.stackexchange.com/q/1877592

The probability increases as the range increases, like you say; the probability that a 3 appears when we choose a random number between 1 and 100000 is much greater than when we pick a number between ...

How can the refractive index be below 1 in a dielectric?

https://physics.stackexchange.com/q/436329

What you are describing is anomalous dispersion . This happens when a material becomes strongly absorbing, typically near an absorption line, and the refractive index becomes complex. In these ...
