Yeah, better you try this at home with a clear mind, draw a diagram and try to see what the question actually means, I am not sure if your method of equating gradients ?? is actually correct, since the question at hand refers to angles other than that from the positive x-axis..
NEW QUESTION (EASIER):
Surely doing this parametrically is faster, but I guess for the sake of trying a different technique it's good practise.
For the first part sub in y=mx+b into the ellipse equation and make discriminant = 0:
howd you find areaFor the first part sub in y=mx+b into the ellipse equation and make discriminant = 0:
yep the correct answer is nope you can't find the limiting sum (what was I thinking?)You do realise that from product of roots
Anyway next question.
Since the diagonals of the rhombus are at 90 degrees
Whats the chord of contact..Since the diagonals of the rhombus are at 90 degrees
Possibly use the chord of contact is my guess that is of the form y=0.
Find the vertices of the rhombus I would suggest.
You haven't done 3U Parameters yet?Whats the chord of contact..
my teacher said it wasnt important so we never learnt it properly...You haven't done 3U Parameters yet?
Don't be afraid to use parametric to solve it, however I suggest using Cartesian coordinates since it makes everything a lot more quicker.
Not important?? Tell your teacher they are an idiot.my teacher said it wasnt important so we never learnt it properly...
Nah he probably taught it.. its probably me not paying attentionNot important?? Tell your teacher they are an idiot.
Why wouldn't you pay attention in class....Nah he probably taught it.. its probably me not paying attention
I can think of good reasons. But if those reasons are correct, I sure hope he goes to a co-ed school.Why wouldn't you pay attention in class....
