agreed theres a typo al; as p varies the locus doesn't change. in the exam my mind was like 'wtf is this questoin'. checked my working 5 times to ensure that i was right cause its such a double reverse trick :/
i wrote the locus is a "vector" and i had the eqn the same as the correct answer...
wth understand and interpret the question? thats nufin in 2u. they spell it out to you in 2u.
e.g. FIND THE TANGENT
keyword = tangent = need to find dy/dx and sub points in
thats bloody obvious - you just gotta pick keywords and solve it. what theorems to use, maybe some of the tricky geometry...
Re: Oh god.... Will I get marked down for writing this as my reason for similar trian
wth bro. equiangluar is the right reason. 'two angles are equal' wtf is that. if you wrote AAA they'd probably give you it, considering its only 2u they wnt really care at al.
