I have 3 points defined on an arc of a circle.I need to identify whether they lie on the major arc or minor arc.How is it possible?
I know the three points.
I know the radius of the circle
That is the point--I have three points start,intermediate and end--if the centre of the circle is within the sector bounded by the three points I need the major arc length else if the canter of the circle is not within the sector bounded within the 3 points i need minor arc
Circular arc--badly stuck
I have a circular arc defined by 3 points [start point, intermediate point an end point].
I know the radius of the circular arc too.
I know the angle subtended by the start and end point at the centre.
I do not know the center of the circle
Now,
I want to...
I need to solve this equaation:
(x1cos(p)+y1sin(p))^2 * (x2sin(p)-y2cos(p)) = (x1sin(p)-y1cos(p)) * (x2cos(p)+y2sin(p))^2 ;
x1,x2,y1,y2 are constants
The equation would have 3 roots
1 real and two imaginary
I don't need imaginary roots.
I am planning to use bisection...
To explain in detail what i want:
Now,
I have a parabola whose 3 points (x , y) are defined as:
Point 1 : (-9, -1)
Point 2 : (-6,6) [VERTEX POINT]
Point 3: (4,-9)
I need to get the length of the parabola.
Now, the directrix of this parabola is not parallel to x axis.OK...

Sorry---I will put it more clearly,
I have a parabola whose directrix is not parallel to x axis.
The equation of this parabola is:
x^2 + 2xy + y^2 - 16y + 32 = 0
I know three points which lie on the parabola [start point, end point, vertex].
Now, I want the length of the parabola
I have a parabola.
Now, i need to get the length of aprt of a parabolic segment--that is a quarter of a parabola or 1/10 of a parabola, 3/4 of a parabola or anything
How is this possible?
Please help
Homework Statement
1.I have a vector defined by (v1,v2,v3).
2. I want to project this vector on a plane such that a point on that plane is defined by (p1,p2,p3).Also, the normal to the plane is given by (n1,n2,n3)
3.Can anyone help me to the projection of the vector on this plane...
Plz help with another case:
1. If V2 and V3 are parallel
2. Hence V1 = the cross product of V2 x V3 evaluates to 0,0,0
3. What is the physical reason for this?
