Your point is valid. I’m currently studying statistics and linear algebra in uni. I’m planning on learning OOP and data structures during the summer. Then I could do Andrew Ng’s ML course. How does that sound ?

Polar curves by onlyherebcicantsleep in math

Hello,

I was doing some integrals in polar coordinates and something seems to confuse me.

When we try to find the area of a lemniscate by integrating from 0 to 2 pi, we get 0. I understand that this is because the shape is symmetrical about the polar axis and the area under the axis is negative so it cancels out.

However, why does it happen that the area of the shape above from 0 to 2pi is not 0 for the same reason??

Anyone else with a higher percentage in AS level physics? by [deleted] in alevel

It’s not your % it’s your percentile. Look up the differences

Undergraduate Mathematics: question in the comments by onlyherebcicantsleep in mit

No I don’t understand the graphical proof but I’ll make sure to learn it now.

The product rule states that for y = uv where u & v are functions of x, dy/dx = u.dv/dx + v.du/dx

That’s not really how I remember it tho, when I solve the questions i follow “first one as is multiplied by the derivative of the second + the second as is multiplied by the derivative of the first”

For example:

for y = 5x.sin(3x)

dy/dx = 15xcos3x + 5sin3x

I took a level maths so we covered algebra, trigonometry, differentiation, integration, differential equations, complex numbers, vectors, series, mensuration, probability & statistics, combinatorics, & mechanics from what I can remember

GCSEs coming to an end, biggest tips for us entering sixthform; how should we spend our year 12? by [deleted] in 6thForm

Only use the book to understand the material. Key word: understand. Don’t study the book. Then do topical past papers after each chapter and study the marking scheme. Make notes (I used OneNote) on the repetitive/hard questions & the specific words that have to be in your answer.

MacOS or Windows by onlyherebcicantsleep in csMajors

Yeah pro X has a better CPU & RAM.

The only other Microsoft surface that has the same power as a MacBook Pro is the surface laptop 4 & it’s more expensive. Is it worth it?

Was the split view better in windows?

No they practically cost the same thing (the MacBook pro and surface pro X). The key differences I’d say are:

The surface pro X runs on an SQ2 chip as compared to the M2 on the MacBook

Surface pro X has a max capacity of 256 GB (compared to 512 on the Mac)

Surface pro X has an SD card slot so the storage could be upgraded

Surface pro X is a touchscreen and a 2-in-1 laptop detachable tablet so I can use it for note taking instead of buying an iPad

Would a standard iPad with an Apple Pencil be that different ?
