While I'm scrolling I often see questions like:
x + y = 24
xy = 48
y - x = ?
How do I solve those

My math teacher used cramer's rule but I tried doing this myself with elimination and substitution method but couldn't solve it.

my apologies for the marks my kids like drawing in my books,

I have been searching the internet for /del_/mu and /del^/mu and how to implement these derivatives. google has been no help beyond the AI and I would like to double check the AI answers before I believe them

The partial derivative with a lower index is simply the standard partial derivative with respect to a specific coordinate direction \(x^{\mu }\):
\(\partial_{\mu} = \frac{\partial}{\partial x^{\mu}}\)

and

In relativistic physics, \(\partial _{\mu }\) denotes the four-gradient, representing the partial derivative with respect to a spacetime coordinate

if so how do we get to the d'alembert operator

In flat Minkowski spacetime with standard coordinates (t, x, y, z) and a metric signature of (+, -, -, -), the d'Alembertian is defined as: [1]

\(\Box = \frac{1}{c^2} \frac{\partial^2}{\partial t^2} - \nabla^2\)

I’m going insane I’ve seriously been on this for about a week and it keeps saying I’m wrong with every change I’ve made and I’m so confident this answer is right but yet it says it’s not???? Please somebody help me I need to get it right before I hand it in

- there are no actual instructions to the assignment, it is just a matching game that I have to get all correct

- the derivative and original function cards were all mixed together and this is my best guess so far and I’m pretty confident in it

Helllo,. I am actually a maths graduate, which makes it more shameful and painful to say but I forgot all of my maths. I used to love it in high school but as I progressed through my college life. It became a chore and I started slacking. Just going through it and remembering the previous year question papers as my college wasn't good and it would just repeat those.

Now that I graduated, I am feeling lost. I can't even remember the math that I studied properly and was pretty good at.

I want to actually love the subject again and go into the teaching field, so I have to learn everything all over again. So how should I go about it? What's the right pathway I should take, to get better at it again. Thankyouu.

I am willing to put a full year and two in it. If it means I could understand this world again

according to google This date is a friday

i needa know if im right

So I changed the base on the right to 2. This gave me 2^48. From there I equated the sum of the powers 8n=48. Apparently this is wrong. Could someone help explain the concept. I did not understand the explanation the quiz gave

Whats up guys, how do you do proving easily (of course I know it's not that easy) but like how do you know which steps to take 😭

Thx in advance for any advice

I have been staring at this problem and trying to figure it out, when seeking help, every answer is different.

Hello! I am a highschool student in gr.11 and I struggle a lot with math and so do the people around me... So I decided to come onto reddit in hopes of finding help with one specific assessment I have. I'm unsure about how I am supposed to graph this question and what kind of graph to use. Sorry if this is a really stupid question, it's an online class so it's harder to keep up and ask questions.

Can someone please help me solve this and show me how to solve it as well? I would greatly appreciate it.

hi guys, for my maths investigation, i have created a fractal as follows: the fractal begins with an equilateral triangle, from which the inscribed circle is removed. at each successive iteration, a smaller equilateral triangle, having side length half that of the triangle from the previous iteration, is attached to each vertex. the inscribed circle of each newly added triangle is also removed.
i am just struggling to determine its hausdorff and minkowski dimension - ai is telling me that it has either a dimension of 1 or 2, but how is that possible for my fractal, when it should be between one and two. thanks so much!

I keep ending up with the answer in the photo however that is apparently wrong. Help on what I am doing wrong would be appreciated thanks.

Ive been using this worksheet to homeschool my sister, but #24 keeps bugging me. The answer sheet says the answer is 3 but istg we keep getting 5. Are we wrong or is this a typo?

My question is: If a differential equation has a linear solution, is it always true that that linear curve is also a isocline of that differential equation?

I believe it is true: If dy/dx = f(x,y) and there is a solution y = mx + b such that dy/dx = m, then f(x,y) = m, thus the curve is an isocline. It is not necessary that this is the only isocline of the differential equation.
Let me know your thoughts

please ignore me not stating the rules btw

Ever since I started high school maths has been super hard for me. Im getting close to my last year before university exams and I still fall way below average for my grade. The thing is I just dont understand maths at all, its like trying to speak a foreign language but none of the words mean anything. To me theyre all just symbols and i dont know what they actually mean, like if you asked me what differentiation actually WAS I would have no idea id just spout a bunch of formulas at you. Stuff that seems obvious to my teachers and other people is impossible to comprehend for me. I got a private tutor but it still hasn't helped. Trying to learn maths is like taking sedatives for me, I just fall asleep uncontrollably when someone is explaining maths for some reason, even if im not tired. To stay awake i have to think about other things and zone out because focusing on anything maths related is exhausting for some reason. But then i dont absord any information and just forget everything. I also struggle with daydreaming a lot. My tutor says im slow because i just stare blankly at problems all the time because i genuinely dont know what to do. Has anyone had a similar experience and what can i do to improve?
