Hey spiral ! do you mind helping me with this question?Feel free to post any more questions up, I have nothing to do for a couple of hours. I am sure others will be able to contribute too.
Err i think the bottom is square root 5, and the answer says its (4 square root of 5) over 5 units :SOf course. First, let me point out something. To find the distance between those two curves (perpendicular). You need three things, a point, a line and of course, a pen.
So looking carefully, we only got two lines, no points at all. However we can see that they are parallel. So the perpendicular distance from any point of each graph to the corresponding line will be the same.
Just get a point!
I will take as my first curve and as my second curve.
On my second curve I will substitute and get . Of course we could use any value but is easy!
Now what do we have?
A curve:
A point:
Use perpendicular distance formula now! Let be the perpendicular distance.
Putting our values in,
Correct! Note that SpiralFlex usually makes the most mistake after 9 pm.Err i think the bottom is square root 5, and the answer says its (4 square root of 5) over 5 units :S
Which program do you use?Correct! Note that SpiralFlex usually makes the most mistake after 9 pm.
What does it mean by collinear points? It means that they line on the same straight line. So, how do we answer this question?Can anyone answer this question please? It seems pretty simple but perhaps my brain is battered from lack of sleep.. Anyways:
A,B and C are collinear points and AB=BC. If A is the point (4,5) and B is the point (1,-1), find the coordinates of C.
Click reply then the fx button.Which program do you use?
Let's see this question, it may seem tricky, but it very easy to understand.New question! Locus:
Given the points A(1,4) and B(-3,2), find the equation of each locus of the point P(x,y).
c. P is equidistant from A and the x-axis.
