Beware a scammer named Stephanie Alexandra Emsworth. She claims to be a "math teacher" but actually she's a fraud. She tutors students but when people ask her basic questions on algebra, she gets the answers wrong. For example, one guy asked her what is the quadratic equation and she said it's a triangle with two equal sides.

What other numbers can be found mixed in with the prime numbers?
Is there a way to remove these other numbers in order to reveal the prime numbers?
I was able to answer all three questions over a three year period. Here are the answers.
The prime numbers can be found in the 12-note octave, specifically in columns 1 5 7 and 11. The columns are created by adding '12' in layers to each of these four bases indefinitely. All the prime numbers (except 2 and 3) can be found within these 4...

I'd really would appreciate it if someone would take a look at this and tell me where I am wrong or have over-simplified things. It's short and a straight-forward approach. (I hope the 2 figures transfer okay to this post. I'll upload a file with them just in case.)

Please can anyone help with these two equations.
I am asked to provide the general solutions.
a) 3^2 y^2dy/dx = 2 − 1
b) 2dy/dx + 3 = −2 − 5
Any help will be greatly appreciated ..read more

Hi there, first time poster here. If I can solve this problem, I can save my sister countless hours in her job, which is great because she's raising two kids and keeping house and so on. At least, that's the plan. I'm working on a function for a spreadsheet she has. Before I do that, I need to crack a formula, from which I will derive said function.
Here's my working so far. As far as I can tell (I'm a gardener by trade and certainly no mathematician) If I can isolate PT, everything else...

Hello! I was very tormented with this Lebesgue-related problem. I searched the whole Internet, but I didn't find a solution (maybe I was looking in the wrong places). The task looks like this:
Is the function integrable by Lebesgue on a ray (-∞,-1)?
if it is, then find its value.
I've tried to find Riemann improper integral...

Maybe the best way to introduce myself is with some math,
I'm a huge fan of the Fibonacci sequence, it's really what cultivated my passion for math. I've been considering the algebraic equation of it and wanting to compare it to the sequence itself to see where it really diverges and by how much. It was interesting thinking about how to compare the two for very small changes, which didn't seem possible for a sequence on first glance, but if we assume the curvature between each two terms n &...

Hey everyone,
I'm hoping to get some pointers on the following problem (screenshot of question and solution attached). The formula describes the motion of a particle in space with the position defined as r = r(cosωtˆi + sinωt ˆj)
It asks me to find the trajectory. In the solution, it solves for the trajectory by taking the magnitude of r
In a different problem, the trajectory is solved for by looking at limiting cases (i.e. in the limit where t -> 0 or infinity)
I don't get...
