I solved it without using c = sqr(2ab). Where is this question from?View attachment 38425
Hi - don't know where to start for i). The solution we were given involved=k(
/a +
/b) which contains unit vectors, which I don't really get. I know that we can't just equate k to c, because that would mean that c is a+b which is wrong as question does not imply a rhombus.![]()
Thanks in advance for your help!
I'm not sure this works because you've assumed that c lies on a straight line between a and b, so you would need to prove this!I solved it without using c = sqr(2ab). Where is this question from?
