Very nice of you to share notes :h:

I have a lot of notes if anyone's interested. FSMQ, etc.

How did you find the physics exam?

Really really easy.

I got a few questions wrong - thermistor (thank god it was a 1 marker :biggrin:), and the nuclear moderator/control rods (I got them the wrong way around :frown:)

How about you?

It was alright, better than I had anticipated

I got that calculation one wrong - I wrote "0.01" as my answer -.- didn't realise it was the wrong units

Somehow I did remember the thermistor, but then I made a mistake converting cm to mm for the paper width one... Careless mistakes what?

It was 0.1mm rite?

35 minutes and I'm leaving for English :frown:

I don't suppose you have any notes on Trig Identities for the FSMQ that I could read?

Yup. If you don't understand them you probably need more practise with them - that was the case for me.

The only ones you really need to know are:

sin2θ+cos2θ=1sin^2\theta+cos^2\theta=1

sincos=tan\frac{sin}{cos}=tan

rearrange as necessary

I'll post my notes now anyway

edit: internet being stupid, can't upload them sorry :frown:

But I can explain anything if you need

Do any of you know how I can wake up with energy? And like feel the need to revise, instead of like dying after 2 minutes? :-(

Thank you.
The bit I don't understand is when you solve theta to get a number, then you have to do certain things depending on if you're looking for the values of sin/cos/tan. How do you know what to do? eg. Add 180

It is to do with a graph. Sin is positive in the first region (where you leave the angle as the found acute one) and the second (180-acute gives answer). Tan is positive in the first and third (180+acute angle) and cos in first and final (360-acute). Look up the trig graph as it will probably help to make sense of what I just said.

If the angle required is negative, then you go to the regions where it is negative, eg region 3 and 4 for sin.

Hope this helps you. I have a slightly inappropriate method of remembering the order I can PM you if you want
Biology was good :biggrin:

Off for 12 twelve days now, but still got my toughest exam to sit. :frown:
