#curvature

In this video, I show how to obtain the curvature of parametric equations that involve integrals, by first utilizing the fundamental theorem of calculus to obtain the derivative of the position vector

In this video, I derive a more convenient formula for the curvature of a space curve, which involves the cross product of the first two derivatives of the vector function. I derive this using the fact

In this video, I go over the definition of curvature, which describes how quickly a curve changes direction at a given point. It is defined as the magnitude of the derivative of the unit tangent vector

A more technical look at earth curvature seen in weather baloon footage. Why flath earth debunkers need to be accurate

Looking into how curved the planet should look and how some flat earth debunkers mess it up.

NO YOU CANNOT SIMPLY BECAUSE IT DOESN'T EXIST AND EVEN FROM SPACE YOU CANNOT SEE IT BECAUSE EVEN SPACE DO NOT EXIST IT'S A FAIRY TALE ONLY, FOR CHILDREN WAKE THE FUCK UP FOLKS! RESEARCH YOURSELF ▶️ DTube

we all know the officially declared "Earth's curvature" since we were told that radius of it is about 6000km. the problem is that when you go to verify those data.. YOU CANNOT FIND CURVATURE

Whether at sea-level, the top of Mount Everest, or flying over a hundred thousand feet in the air, the always horizontal horizon line always rises up to meet the eye-level of the observer and remains perfectly

I know I know...you will probably think I am an idiot, but please check out this interesting video and tell me if it is really impossible that the earth could be flat or at least has another curvature!
