Well, I feel it's good to question these things ... question everything. Okay, we have the observation ... we have the mathematical relationships describing it ... so, now let's do search for the mechanism causing it. Time is merely a measurement relative to a frame and something happens to that...
Of course you remember the very pretty song There She Goes. It's now even prettier with the accompanying images advertising Ortho Tri-Cyclen Lo. Images which appeal so strongly to our own self image and needs show that advertisers do indeed know how to effectively reach us. Also, notice the...
Yoplait has given a really nice photographic theme to the oldie, Itsy Bitsy, Teenie Weenie, Red and Yellow Polka Dot Bikini ... absolutely delightful little bit of telly advert.
Have you seen it?
This is really neat. In Calculus - Early Transcendental Functions, 2nd edition, by Larson - Hostetler - Edwards (Chapter 4, page 322, Problem 107), the question opens with this statement:
Archimedes showed that the area of a parabolic arch is equal to 2/3 the product of the base and the...
Wow. I really like HallsofIvy's response. I am so, like, very impressed. and I also like the "divide proportion". That is so very clever. Henceforth, I, too, shall refer to the "divide proportion". I love it! Thank you HallsofIvy. Hugs. -CeeAnne-
I am not attempting to develop a theory. I am speaking against what I view as a misapplication of other theories. There is a difference between demonstrating that clocks slow when in an accelerated frame and actually returning to, say, 1960 and having everything the way it was. The illustration...
I view time as merely a comparative measurement, much as divisions on a long, flat object can be compared to to another object and we can say that the object is so many centimeters this way or that. Measurements are mathematical values.
Tman, I don't believe it has to do with Newton. I believe the question is asking for the distance from the point on the ground beneath where the ramp or trough is at 20cm to where it meets the ground at 0cm. On the xy grid, where x=0, y=20, that's where the ball starts ... it rolls down the ramp...
Oh, Mr. Mason, that is truly fantastic. I am so impressed. And the answers agree. This is amazing. I really do appreciate what you have done for me. Thank you ever so much. Hugs. CeeAnne
Mr. Mason, since we know the radius, and it would be the same radius for a sphere, and the curler would roll perfectly on the sphere, and if we rolled it exactly one revolution; isn't there a simple method to determine the area it rolled on? I mean, we can also determine the total surface of the...
I discovered the parabola rule, empirically, years ago while playing with simpler area under the curve problems. It seemed there ought be something for parabolas because there was an area formula for the ellipse. So, I experimented to find something similar. It wasn't complicated and it seemed...
Resistance Formula
Aratnaus. I believe you should have started a new thread, but since we are here ...
Effectively what you form with the equilateral triangle is three 6 ohm resistors, 18 ohms divided into thirds, so the resistance across any two points would be equivalent to a 6 ohm resistor...
This isn't homework. It's maths curiosity.
I have a hair curler set. The curlers are spool shape, 3 inches long, 1/2 inch diameter ends, 3/8 inch at the middle.
The surface is a surface of revolution. The curve generating the surface is a circular arc, concave on the curler. Assume a smooth...
