Can we assume that P0=-P2?

When you use the definition of the trig functions with the right triangle, then you have: tan(a)=y/x Where a is the angle, y is the opposite, and x is the adjacent side. If you go by this definition of the trig functions, and you do arctan(y/x), would you get a in radians?

Would the arctangent of y/x give you the angle in radians?

Lift drag, I meant. The lift drag, or induced drag, would be small because of the other factors that go into it. And also, what about the other graph? There is an intercept for that. I don't even think it shows the intercept on the other graph.

I also can't post links or upload things.

The other terms can be described as slight because first, the wave drag coefficient is only for supersonic speeds. Second, there is most likely little, if any lift. Third, this leaves us with the skin friction and for drag, and the skin friction coefficient should not be very high. And I used 2 different variables to prove a point

This thread should have been on density and not on relativistic mass. That should be another thread.

The functional form changed because what you have is an angle of attack from the front and back, angle a and angle b, making it 2Cf0sin(a)-Cf0sin(b) In the angle of attack, a=b, and simplifying makes Cf0sin(a) It is most likely not 0 at all, actually. It may seem to go to 0, but there is a slight y intercept that is the other effects.

One thing no one has answered is my argument with the higgs field. Mass is a measure of how much something interacts with the higgs field, so therefore, if something is moving, it interacts more with the higgs field, and so, more mass.

I have lag and computer issues, so It won't always be what I meant to write. Correct me when that happens. And for the energy equation, mass is a measure of the amount of energy an object has, according to Sean Carroll. If an object has more energy from moving, it therefore has more mass.

The change in x would be negative, but that doesn't mean that the length would be negative. Basically with the spring, you have this: |||||||||||||||| When it expands, it is now this: | | | | | | | | | | | | | When you compress it again, it goes back to it's previous state. Now, let's explain this with vectors: | | | | | | | | | | | | | Compression <-- --> Expansion If you assume the direction of the compression is the same as the expansion, then it would be negative. But, since it is not, then it would be positive in that direction, and negative of the expansion vector. In fact, it is more like a 1 dimensional vector field.

You know how mass comes from the higgs field? If you have an object moving through the higgs field, it is interacting more with the field, and so, it has more mass.

Would that be an actual measure of negative length? No, that still counts as a change in direction. You are talking about vectors.

I don't mean negative lengths as in direction, I mean negative lengths as in the measure of a length to be negative

When things are accelerating, the velocity is: v=at/(1-a2t2/c2) You can use this for the relativistic mass. But, I agree with decraig And also, why would energy be mc2y if the actual equation is E2=m2c4+p2c2 ? But now, let's assume it was mc2y. It would not be mc2 and would be mc2y because of the increase in mass.

I will base it off of things such as metrics. And also, I have looked into it, and have found no negative length theories.

when you get close to light speed, it takes more then four times the energy to double the velocity of something, even though the equation for kinetic energy is 1/2mv2 . This is because of the mass increasing by a factor of gamma, making it take more energy. And also, when you have a constant force acting upon something, the acceleration slows, even though you have the same force acting upon it. This is because of mass increase.

And also, how do I have crackpot threads?

Oh. I will try to make a theory for negative lengths. And the theory wouldn't just include lengths, it would also include negative space, which will be defined as space where all the measurements are negative, and also space with positive and negative measurements.

I mean on the forums

Why can't I quote in windows 8.1?

I mean negative length as in if you measured something to be negative length, and not as in a number line.

I would basically be asking something like that. I was wondering if there was a mathematical system to describe negative lengths. And also, if there were negative lengths, would they theoretically be in negative dimensions?
