25% study, 75% games? Haha

Just Math?

Ahh. Alrighty. Thank you everyone! Much appreciated.

So T must be given?

I get how to find g using gradient, but how would you find T? (Just in case).

Can they ask us to mathematically calculate the Period (T) using the gradient or just the g?

Yeah I get the gradient value (rise/run) first, but then I don't know what to do with it.

Hello, I'm just confused on how you use the gradient with the formulas to find g and T. I know that the formulas T = 2π√(l/g) and g = 4π2l/T^2, but not sure how to sub in the gradient. Can somebody please help me? Thank you, Parrot

Alright, thanks guys!

I use e.g u(x) = 50cos(30), but when I get range and stuff, I'm not sure if I write the whole thing in or just rounded off?

So you basically don't have to show exact figures, and can write on the paper a rounded value of e.g. 7.23412445m to 7.23 (2.d.p.) or 7.23412445 * 10^3 to 7.23 * 10^3?

Hello, In Projectile Motion, is it important to show your full values (e.g. 7.23412445m) or can you just round it off? Thank you, Parrot

Hello, Is it easy to teach yourself 4U Polynomials with understandings of Complex Numbers? Thank you, Parrot

Hello, Which ones are better to study with? (Especially when you just learnt a topic). Thank you, Parrot

Hello, I was just wondering what raw mark you need for a state rank in Engineering. Thank you, Parrot

http://4unitmaths.com/lectures4u.html Although 4U is probably best done by practice.

So can I use the worked solutions to actually learn the concepts?

Hello, Learning like that in 4U (Arnold/Arnold) then past papers? Thank you, Parrot
