Hi I have a line determined by P1(x1,y1) and P2(x2,y2). I also have a point P3(x3,y3). I need to find the formula of the distance from P3 to the line, and also...

Hi Adi ... You could work out the equations of the two lines and find their intersection point as simultaneous equations. There is also a more general solution...

Is there a geometric proof for the sum of two cosines? (i.e. prove the identity cos(A) + cos(B) = 2cos1/2(A+B)cos1/2(A-B) geometrically)...

Interesting question!!! Geometric proofs exist for cos(A+B)=cos(A)*cos(B)-sin(A)*sin(B) and cos(A-B)=cos(A)*cos(B)+sin(A)*sin(B). Adding these two equations...

Thanks Carl. Yeah, I knew that the substitutions lead to the sum-to-product identities, but was wondering about a geometric proof. I know you can use the idea...

Hi Neil ... The volume of a cone in terms of radius and height is V = 1/3 * PI * r^2 * h The angle is 60 degrees at the apex, and so h / r = sqrt(3) r^2 =...

Thanks Alberto, 60 degrees is the angle of the apex, so a vertical slice through the centre of the cone (eg left to right) exposes an equilateral triangle and...
