Anyone help on the first part of Vector Q?

Anyone help on the first part of Vector Q?


I found a vector perpendicular to line via dot product,
then set up a line in form r=a +Xb with a =p and b=perpendicular
I then found value of X up to intersection, doubled it and subbed it back in to find P', anyone agree with this

This is how I did question 1:



fffffffffffffff

That's so simple. I hate exams. I only made one substitution (x=theta+35) and got my answers in terms of tan35 and tan53.

Area = sinx * (cosx)^3

That cannot be bigger than 1...

FML I just realised I wrote down 2^4 = 8
Answer to 3(c) is 70, surely? (k = 6, p = 4/3, q= 3/5, let n go to infinity). (I assume this is the sum question - question numbers are missing in the 1st uploaded page).

Oh sorry I think I got 70 but wasn't really sure - I subbed in p = 4/3 and q = 3/5 and k = 6 into part b)

I wrote S/6 = <stuff>, then multiplied by 6 at the end - thought it'd give the same answer

It does, assuming you don't make any mistakes.
