>there are people on this board who actually believe race doesn't exist

Khan Academy was a mistake. My kid's school has been forcing them to use it during COVID and it's terrible.

I don't mind doing this, but I work from home and I can't be with him 24/7 while he does his work. Are there any resources you guys know of for kids when it comes to math? I already printed out worksheets for him. Videos are preferred, so he at least pays attention.

you must be sub 70IQ to post here

11th grade, I literally have an A+ in every single class except geometry. In Geometry i have a F.

What should i do to learn? My SAT is going to get raped due to the fact i have a 6th grade math education.
/Sci, help me

I want to check if the improper integral [math]\int_0^{infinity} e^{-x^2}[/math] is convergent or not. My first step is comparing it to [math]e^{-x}[/math] which is obviously convergent, but is that mathematically sound to say? I'd like to compare the function to [math]x^{a}[/math] to have a sounder argument but how do I do that?

One of them is an hour long talk which gives a broad overview and allows for questions and interaction between me and the person giving the talk. The other is several hundred pages papers on a subject I have little understanding of and potentially little interest in.

I need to raise my IQ by 30 points immediately. How can I do it?

i must be the most retarded guy in this board at the moment, here's the story:

>2nd carreer atempt
>previously journalism (dropped coz depression meme)
>interested in electronics and shit, have done a few things
>think about engeenering
>still so, don't study to the admission test
>didn't get in
>yet enter study in the best college in the country (latino shithole)
>desing
>yes
>fucking desing
>think about my interest and tell myself this will be enough
>first day of class
>everyone is retarded
>everyone strugling at basic trygonometric
>feminist commies start a strike where men is not allowed to vote.
>they start complaining about right they already have
>lose 2 two months of class wich i still had to pay
>the only faculty actually working is engeenering and med

i'm planing on taking engeenering classes so i can slowly change my carreer but i don't know wich is the best field, pls tell me there's still hope for someone like me.

>Infinity isn't a number you can graph

Is Mathematics derived from Logic; or Logic from Mathematics? if the former is true, then Philosophy, being derived from logic, would be as high-level as Maths, making the scientific method a philosophical lens to view the world. If the former is true then Positivism is undeniably false.

Before you argue on behalf of the latter think about the model you will use to prove your arguement, is it a logical one or a mathematical one? And if this question relates to the root of all things and can only be proven logically, then logic is the root of all things.
