I was wondering that, too.

I am under the impression that most mathematical notation is uniform throughout the world.
I once went to an Indian School, although the school was English based, they called some of their concepts by different names!

Yeahh...I can't think of a specific example right now, but I remember noticing that certain conventions used in like, mechanics, differed between here in the UK, and America....but I'm pretty sure the notation of tanhx is the same everywhere, lol (I was under the impression that the h was for hyperbolic? They can't change that!!...)

I was just wondering if I want to be a biologist/research scientist. Up to what level math do you guys suppose I would need?

A molecular biologist?! How cool!! Though I'm pretty sure in depth knowledge of calculus won't be crucial for it, lol...

No, it's cos instead of sec.

Really? I thought it was ln|secx| too...the integral of tanhx is ln|coshx| (+c!), though...

nope, ln(cos(x)) is the integral of -ve tan(x).

Hmm, could be, we started on this integral thing only 3 days ago.
what about the ∫f'(x)dx/f(x) = ln|f(x)| + C
so when you have tanx = sinx/cosx, and cos'x=-sinx, so basically you have ∫(-(-sinx/cosx))dx = -ln|cosx| + C
??
 
its easier to have a go when you have the table of integrals ...thats what helps me otherwise im no good :(

That's what I'm hoping!

Chemistry and phyics are much less uniform.
I have no idea what a cosh or tanh is.
 
yeah its not bad...i need to catch up on differentiation cus i slept on the days the lecturer was teaching it

Yeahh, true...and wellll, they come under 'hyperbolic functions'...differentiating and integrating them is quite similar to with trig functions, but they're totally different in most other ways...don't worry about them until you have to, lol...
 
Sorry guys if I interrupted a tutoring course for someone here or anything, I thought it was a general quiz, I didn't follow the whole thread.
Anyways I would be glad to help out in math related problems.

what are your plans on further education?

hopefully to pass this year inshallah ........but i need to overcome laziness and that i open books and study more often....this the only way i could pass and if i dont fix up ...then off to the jobcentre plus :(

Yeah, but what do you want to do in life?
