The whole solution is a bit long, which I'll attach but the part I'm stuck at is, assuming everything else above it is correct, is 4 < (log x - 3)(8-log x) Note ; inequalities aren't technically taught yet in the course, so please try to make the solution not go too deep into that. If that...

Thank you, I understood that one. and I have to say I cannot understand half of the replies in here, it really blew up. But well it is entertaining to read through them and many facts pointed out such as there are different definitions for the same functions of angle are interesting and kinda...

Well I'm allowed to use anything, I'm just doing it for my own satisfaction. Tho i have no idea about Taylor series.is it possible to clear the basics in a few hours? As for the other point while I've thought about it, I have no idea on how to apply the idea to the proof because I only have...

How do I do this from here without using the derivatives of sin or cos ?

What I meant wasn't that it's too advanced. It's like stretched out over a whole bunch of pre requisites and side topics which makes it harder to cover during a short amount of time. Well it's fine, I'll look it up. Thanks for the link, looks very usefull.

While this is usefull, this isn't exactly what I'm looking for. I need something that's more focused on the graphs and equations of graphs, how they're derived, the calculations, applications etc. Starting from the basics like stright lines and dots and all.

Can someone provide me with some free resources (classes, books, notes, sites anything) for co-ordinator geometry? I want to study it from the basics while understanding the logic of every step and build upto start of collage level. Note ; non free resources are welcome too, but free resources...

I was hoping for a reply from someone who has tried these books. Because you know, Many sites give different books, and I don't know which are actually good and usefull. Thanks anyways.

I'm just done with 12th and I would like to prepare for the bmath entrance exam for ISI. I need some books to prepare and build the basics. So considering there's approximately an year to prepare, please give some good book suggestions that are not too rare and too hard to find in bookstores...

Since the division of units are legitimate, we name derived units as per that, like kgm/s2. But m/m is just one. Even if that is named as a unit, then shouldn't every unit that gives the result one have the same unit name? But that is apparently not the case since sterradian=m2 / m2= 1, and...

I don't understand this, sadly.

I think it might be more efficient and effective if anyone can provide any videos or simple articles about the topic, because I cannot comprehend the idea

By a ratio, I mean that the units are canceled out. As for kat, this is the first time I've heard about it, but mol/s is a derived unit as per my understanding so they're different. Sorry if it sounds stupid, but I still don't understand why they're considered derived units when there are no...

Got What dimensions are, thankyou As for radians and steradians, they can be considered the name of a ratio rather than a unit then?

What exactly does dimension mean here ? What should I search to find more information? And since derived units are derived from fundamental units, How can steradian and radian be considered derived units? sorry for the late reply
