If from our point we were translate in twice the direction of unit normal scaled up by the distance from line to point we would reach the image point. Hence the image coordinates (I) (I)

 

After working out the problem check to see whether your added values are greater than less than or equal to the r^2 value. If it is greater then the point lies outside of the circle. If it is less than the point is inside the circle. If it is equal the point is on the circle.

 

If line through point $P (a 2)$ meets the ellipse $\frac {x^2} {9}+\frac {y^2} {4}=1$ at $A$ and $D$ and meets the coordinate axes at $B$ and $C$ so that $PA$ $PB ...

 

As I understand the rotation matrix around an arbitrary point can be expressed as moving the rotation point to the origin rotating around the origin and moving back to the original position.

 

Here is the question: The distance d of a point P to the line through points A and B is the length of the component of AP that is orthogonal to AB as indicated in the diagram below. So the dis...

 

J'espere bien que t'as des droits!!! je reve il arrache la mauvaise dent! il faut demander un dedommagement : par exemple le paiement complet de l'implant pour remplacer la dent arraché a tord...et peut etre meme autre chose pour le prejudice.

 

This is a giant covalent structure. Lots of energy is required to overcome the strong covalent bonds so silicon has the highest melting point. Phosphorous (P 4 Mr = 124) Sulfur (S 8 Mr = 256) and chlorine (Cl 2 Mr = 71) all are molecular substances and so are bonded to each other by van der Waal forces.

 

Line l crosses through point A and meets the x-axis at point P. First thing to do will be to work out the gradient of OA = 3 As we know the tangent perpendicular to the radius of the circle (OA) and so the gradient of the tangent and radius must multiply to give -1 and so as the gradient of OA is 3 the gradient of the tangent is -1/3.

 

Find vectors a and d. Here is what I have so far. a was easy to find as it is literally just the vector representation of point P from the origin. a = 2 i -3 j +1 k. What I think I need to do in order to find a normal vector n of the plane (which I'm not sure how I would do and I think that's what's really keeping me from progressing).

 

If n n $\mathbf{n}$ is the normal vector to the given plane and p p $\mathbf{p}$ is the point through which the line is supposed to pass then the equation of the line will be of the form r =p + tn r = p + t n $\mathbf{r}=\mathbf{p}+t\mathbf{n}$. You already have both those vectors so you don't need anything else.
