4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

Well, they express y, then find the equation of tangent.
To be honest, implicit differentiation would be easier here.

[lament leaf]

i think so too

idk why they did this

[lament leaf]

im doing high school calc, would knowing this weird method be essential for high school calc or can i just know the second way which if just implicit

[silver sparrow]

Well, it is still correct, just takes longer.

[lament leaf]

its similar to the annoyingly long f(x+h)-f(x)/h thing when its faster to do dy/dx

[silver sparrow]

Well, this isn't a weird method. Technically, you would do this if you don't know implicit differentiation.

[lament leaf]

do you think its essential to know?

if one does have knowledge of implicit

[silver sparrow]

It is useful.

[lament leaf]

understood

also thank you very much you've helped me with every calc question so far

i really do appreciate it man

[silver sparrow]

Don't really know how essential that will be to you. Depends on what you are going to do in the future.

You're welcome!

engineering not mathematician

which is why im a lil on the ropes

[silver sparrow]

Ah, I see. Hm...
Don't know much about engineering, as I'm a chemistry major, but I'd say it's probably required to know eventually.

[lament leaf]

hmm

thank you i will look into it

painful man, these proofs are the harder part

[silver sparrow]

Yeah, proofs can be quite tricky.

[lament leaf]

also if you dont mind, how are you so good at mathematics as a chemistry major

im curious i apologise

[silver sparrow]

Well, I just like math too 😄

I do have some lectures from my previous uni, I can share them. They are in Russian, though.

[lament leaf]

russian smh

know enough to say hi, not enough to watch a whole lecture

[silver sparrow]

Well, they are PDF files.

Still, yeah, that won't really work.

[lament leaf]

google translate?

[silver sparrow]

Nah.

Better to just look up some textbooks in English, or whatever language you prefer.

[lament leaf]

if you find any good calculus notes

or if you have some

id really appreciate it

[lament leaf]

textbook... ik too much for a textbook

its bits and pieces i am weaker in

[silver sparrow]

Hm... Well, some books have exercises.

[lament leaf]

true

rn im just watching a youtube course on it but yes

a textbook might be better

[silver sparrow]

Yeah, I'm not a fan of studying by videos.

Lectures and books are better in my opinion.

[lament leaf]

why

my dad and teachers often says that too, but never understood the reasoning

[silver sparrow]

Eh, not sure. I think lectures are the most important, as you can talk to the lecturer about anything.
As for books, they are more standardized and checked, as well as used by a ton of people.

That's what I'm used to, anyway.

[lament leaf]

huh
