Distance along a latitude and distance along a longitude use similar formulas. DISTANCE(d) FORMULA d = (theta/360°)×(2πR) theta = angle between two points on circle R = Radius of circle For the first question on distance, theta = 360° and R = radius of latitude 50°N. Now radius of latitude = radius of earth × cos(angle for latitude). Because the radius of latitude is not same as earth's that is why formula changed. Also, the first part was not included because 360°/360° = 1. For the following question, theta = difference in longitude and R = radius of longitude (earth).

Well presented 👏👏
Nice presentation
Would like to know the name of the software that you used to do the presentation
Krita is the app we use to do the writing.
2016 paper y did we change the formula for distance of latitude is it because we found the small r thats y we live cosx?
Distance along a latitude and distance along a longitude use similar formulas.
DISTANCE(d) FORMULA
d = (theta/360°)×(2πR)
theta = angle between two points on circle
R = Radius of circle
For the first question on distance, theta = 360° and R = radius of latitude 50°N. Now radius of latitude = radius of earth × cos(angle for latitude).
Because the radius of latitude is not same as earth's that is why formula changed. Also, the first part was not included because 360°/360° = 1.
For the following question, theta = difference in longitude and R = radius of longitude (earth).
