Brilliant, Nick and geogebraHi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20130419 02:41:58

I got it without vectors...

Re: Brilliant, Nick and geogebraI know that and I have been waiting. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Brilliant, Nick and geogebraWaiting? For my solution?

Re: Brilliant, Nick and geogebraIt might help Bob to know what the correct answer is. I think once he gets the sides to 12 he will get it. In mathematics, you don't understand things.

Re: Brilliant, Nick and geogebraWell, I just noticed that the point where the circles touch is on the same line as A and B (because they are the centers of the two circles), and got from that that R=AB+r, that is, AC=AB+BD. Now we can use the Cosine Rule to get ,where alpha is the acute angle of the rhombus. We can get from that equation the cosine of the angle and thus also its sine. We then use the formula for calculating the area of parallelogram using its sides and internal angle.

Re: Brilliant, Nick and geogebraABD with the angle alpha and ABC with angle 180alpha.

Re: Brilliant, Nick and geogebraOkay. Post when you get the equations.

Re: Brilliant, Nick and geogebrahi Stefy, Triangle ABC Using R = 12 + r this becomes Eliminate alpha by adding Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #18 20130419 08:03:18
Re: Brilliant, Nick and geogebraHm, how did you get the second to last row?

Re: Brilliant, Nick and geogebraAh, I get it. Great! Do you use SketchPad to get the area?

Re: Brilliant, Nick and geogebraOkay. If you leave the surds as is without simplification you will also get the exact answer of 108.

Re: Brilliant, Nick and geogebraDon't you mean 108? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #24 20130420 00:10:00
