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...
Damn, it has sure been a while... I just realized today that it's been 12 months since I last went out with a special lady, but I am pretty happy to be...

Hi everyone, I don't know if there are any active members around here but I have a problem that is beyond me - I'm hoping some kindly geometry wiz will smile...
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 =...
... If it´s a spreadsheet, then you can make the Evil Thing calculate for itself, using the solver option :-) ... Please define what is "angle". Is it the...
Oops. Delete the previous message. I forgot the 1/3 in the volume formula!!! Please define what is "angle". Is it the angle between the axis and the surface of...
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...
