As I told you earlier Ryan, we can't tell what you're asking ...

Frankly, I can't figure out what Ryan$ is trying to say! If x= y and x+ z= f then you can say that y+ z= f because "x" and "y" are...

We have said before that what "same" means depends on context. In elementary algebra, it generally means that two sets of symbols...

I agree with Dr. P that we need to see the specific problem to do anything concrete. In general, however, your questions frequently...

Wow. The second link is a powerhouse. It would take me a week to grasp it fully. Thank you for the link. By the way, I have an...

Please quote the actual problem you are working on here, in its entirety. That will make all the difference. In particular, we need to...

Here is the proof you are asking about, with comments: https://mathcs.clarku.edu/~djoyce/java/elements/bookI/propI4.html I also found...

Once again, example would help. x = y means the 2 variables have the same value.

"x= y" means that "x" and "y" are two symbols both representing the same number ("same" here having its usual English meaning). Some...

You have all of those backward. f(x) is the value of the function when evaluated at x. Starting with the first one, it needs to be...

To be more frankly here, I know my skills and I'm not that good much at math and LOGIC , Everyday I struggle to be better and I read...

You started with v = dr/dt = (du/dt)*(dr/du), and you claim that dv/dt = (d^2u/dt^2)*(d^2r/du^2). But you didn't apply the product rule...

"x= y" means that "x" and "y" are two symbols both representing the same number ("same" here having its usual English meaning). Some...

Thank you a lot for the help. I'm searching not for a person who ''invented'' but for the history of cone. How it was used in the past...
