Title: Really need your advice
Post by: studynotes on October 25, 2012, 12:07:55 pm

Just need your clarification of some of the issues im having:
1. is the lead im using a bit too light?
2. for Q2b. is it okay to use an arrow like I did to show my working out?
3. for Q3 do i get the full 4 marks for using my CAS in the second line without integrating by hand?

thanks in advance :)

1. Dont worry about the pen i'm the same it's not like some old marker with glasses is gunna say "can't see it...... 0 marks"

2. Arrows are good i use them all the time i've seen VCAA markers do them in example questions

3. Its calc so no need the question does not explicitly state "show with calculas"
   
    1 mark for integral
    1 mark for c value
    1 mark for a value
    1 mark for b value

1) Please use pen, it's just much safer, much easier to read and just less controversial if something does happen.

2) Yes, the arrow is fine

3) No, include the antiderivative, you might or might not lose marks, but what do you lose by including the antiderivative?
