hi guys,
i have a question.
i saw this picture, and i don't really understand how they derived with the formula. The aim is basically to find the formula for the surface area of a spherical cap.
why do you differentiate the x=sqrt(rˆ2yˆ2)? how does that help to find the surface?
and then next, what role does 'ds' play in here ?
and how do you know that Sy= 2pi (∫cd) x ds?
im really confused and appreciate your answers
