From General Relativity to Dark Energy
If we insert the values from (2.9), (2.10), (2.11) into (2.5) & (2.6) how can we get (2.13) & (2.14) ?? I need to see the calculations step by step.- Adwit

Undergrad How Do You Derive the Distance Formula for a Hyperbola?
In the picture, ρ is not written. I didn't know either ρ is the connector line from the origin to point B or A or it is any other line ? I didn't know which line is ρ . I wanted to know which line indicates ρ .- Adwit

Undergrad How Do You Derive the Distance Formula for a Hyperbola?
Of course, distance is a thing you can see. When I draw a line which connects two points, that line is the distance either it is in hyperbola or circle. That is what I mean by saying " we see distance". Understand? That pictured line is the distance. Everybody in the world thinks that the...- Adwit

Undergrad How Do You Derive the Distance Formula for a Hyperbola?
Gaussian97 , In the case of circle geometry, we see distance r. Where is the distance ρ in hyperbola picture? Is it from the origin point to point B ? Now I hope you understand my question.- Adwit

Undergrad How Do You Derive the Distance Formula for a Hyperbola?
vanhees71, I know your math. I just want to know where is ρ in the picture of the hyperbola ? In the case of circle geometry, we see distance r. Where is the distance ρ? Is it from the origin point to point B ?- Adwit

Undergrad How Do You Derive the Distance Formula for a Hyperbola?
I do the math. Constant becomes 1. But the screenshot of my question shows that constant is some kind of squared distance ρ ^2. Can you show me where is this distance in the hyperbola picture?- Adwit

Undergrad How Do You Derive the Distance Formula for a Hyperbola?
Don't bring special relativity or any physics ( ct or Lorentz transformation ) in here. I want to see the problem from the mathematical perspective, not physics perspective. Where do I find the derivation of distance formula of hyperbola? Forget physics. How do I derive it mathematically?- Adwit

Undergrad Rotation problem in Quantum Mechanics
With all due respect hilbert2, isn't the plus sign of 1st "sinϕ expansion" actually going to be minus sign? I indicate it with red colour. By the way, thanks for your explanation.- Adwit
