which one was it?

The P coordinates.

The P coordinates.

0,-4.61

yeah well addmaths is sooo easy. Today I am sure to get 78/80. I spent an hour reverse checking all my answers.

Same here. Spent 1 hour doing the paper and 1 hours checking.
Yeah, Add.maths is easier and LESS prone to errors than Maths.

0,-4.61
??

Yeah. I wrote -4.6.

 

[mohdumar]

Yeah. I wrote -4.6.

Hmmmmm i can only wish u goodluck.

 

[Saad Mughal]

In a 4 mark question that was pretty lengthy. The examiner might deduct a mark for this! What luck!

oh so like everything except matrices and kinematics

I'm giving you the usual pattern of things in the papers. What came today won't come on Paper 2 most probably.

Not yet. ALHUMDULILLAH. There was just one thing. I gave a certain answer to 2 sig fig. rather than 3 sig. fig.

U always make mistakes which are too silly. Man u always tell us that working in 4 sig and answer in 3 then hat happened?

I did everything right but don't know why, I read the value -4.6009 from calculator rather than -4.6073 which resulted in this.
I know, I do almost everything correct, just these silly mistakes.

I left it in terms of pi...they did that in red spot so I assumed we could do it

There was no pi in final answer.

 

[Saad Mughal]

There was no pi in final answer.

There was, the y-coordinate of P was (3pi/4 - 30)/6. This had to be simplified.

this is an expression. i meant that it was not something like 2pi/3 or something that CAN be written in this form. but this was an expression which must be simplified as u said.
well, lets pray that we get 9A*s inshallah
(although i can see B in english)
