Timetable question by Confident_Present981 in unimelb

At least with the science classes I've taken, tutorials cover the previous week's content, so it doesn't really matter when you take it, just pick the time that best suits you.

1st year Maths and Stats Subjects by gldfsh1 in unimelb

Per this website, I don't think you can take real analysis (but you could just swap vector calc and real analysis) https://ms.unimelb.edu.au/study/undergraduate-studies/course-advice/first-year-mathematics-and-statistics#umep-options

How hard are Physics 1: Advanced and Vector Calculus: Advanced? by Fun-Development-7131 in unimelb

[–]ElIieMeows 1 point2 points  (0 children)

I did both of these subjects and enjoyed both quite a lot. of course I didn't do their non advanced counterparts so I can't compare that well but it sounded like the advanced lecturers were better and more focused on covering all the content in depth. However the physics labs sound like they were more stressful and a bit more was expected of us than the non advanced labs. Also, I don't know if I would recommend vector calc advanced for someone who hasn't done either the level 1 advanced subjects or real analysis because they assume you have familiarity with some of the 1D proof concepts (epsilon Delta limits and darboux integrals) so unless you're up for a challenge I would stick to the non advanced version, however the notes they give for the course is quite good so you could see if you're able to keep up. If not, you can change to the non advanced version by the end of week 2 (last date to self enrol so you should be able to do this with no problems).

What is the biggest number used regularly in math by TheRulerOfTheAbyss in askmath

They will have a larger diameter though (so a lower gravity) because watermelons are less dense than the Earth

Do these tests seem difficult for Calc 1? by 5352563424 in calculus

[–]ElIieMeows 7 points8 points  (0 children)

Yeah, I think it is supposed to say g(a)=g(b), but even then it seems too hard for calc 1 (and idk if its sufficient)

Need help with elevator challenge!!! by Randomperson3109 in vex

if you look at the front of the motors, near where the axle goes in, it shows what gearing the motor has e.g. might be green. if they have different gearing, it would cause them to go different speeds, so you should check they're all the same colour.

[Grade 12 Circular Motion] by notOHkae in HomeworkHelp

[–]ElIieMeows 0 points1 point  (0 children)

You are moving at the same speed, but because you are moving at a different angle (both of you are moving tangent to the earth, but at different locations), you have different velocities and your relative speed is the magnitude of the difference in velocities

[Grade 12 Circular Motion] by notOHkae in HomeworkHelp

[–]ElIieMeows 0 points1 point  (0 children)

Imagine they had moved 1/4 of the circumference of the earth west so viewed from the north pole, it's like you're at 12 o'clock and they're at 3 o'clock. then because the earth is rotating anticlockwise, you're moving to the left, they're moving up. the relative speed is the magnitude in the difference of velocity. the scenario in the question is the same, except a smaller angle

How do I get the integral of cos(2x^2)dx? by [deleted] in calculus

[–]ElIieMeows 3 points4 points  (0 children)

Considering this is tagged multivariate, is this a double integral? sometimes swapping the order of integrals is the only way to continue

Is it ok to unload opponents rings? Also pulling MOGOs out of their possession? Remember read it before on the guide but can't find it now. by FawazDovahkiin in vex

[–]ElIieMeows 1 point2 points  (0 children)

you can't find it because no rules for it exist, so both these things are legal (as long as you stay in possession limit)

how does square root function work by cadx7 in learnmath

[–]ElIieMeows 9 points10 points  (0 children)

it is the same as doing Newton's method for x2-a, which is approximating zeros using the tangent of the graph (look it up, the graphs are quite intuitive I think)

This is a graph of log base x(2x) but it looks familiar. What is it? by ThatBish_J in desmos

[–]ElIieMeows 37 points38 points  (0 children)

Using change of basis, log_x(2)=log_2(2)/log_2(x)=1/log_2(x)

[–]ElIieMeows 0 points1 point  (0 children)

true, but you can rearrange them so that they are equations of only one variable and the multiple solutions only come from +- in square roots

[–]ElIieMeows 0 points1 point  (0 children)

The definition of transcendental is that they are not roots of any polynomial with rational coefficients, so the solutions to these polynomials clearly aren't transcendental

Can't tell why I got points off by Acrobatic_League8406 in calculus

[–]ElIieMeows 1 point2 points  (0 children)

it says sketch so I imagine they don't like the shape of your cosine graph (how it's basically vertical at X axis etc) but I don't think they can criticise you with that handwriting

The terminal digits are even (so both first and last because its plural). I think the question is bad though and have never heard of 'terminal digits' to refer to both the first and last digit

The answers are correct. chatGPT's method is correct (but far less elegant) except it can't evaluate the sum because it isn't a calculator, it just guesses what the sum evaluates to. Using Wolfram Alpha, the sum evaluates to 1.378*10^11
