I've to show , " at the spring equinox for a place of latitude ø, the sun will become visible at the top of a tower of height " H " feet, about(adsbygoogle = window.adsbygoogle || []).push({});

" 13.94(root over )H * sec ø "

But as far i made calculations, i got the amount of

"4.24 root over H * sec ø "

I used all the measurements in feet but i could not derive this amount of 13.94 instead of 4.25. .

Plz someone held me to obtain it. .

I used this formula

" root over (2RH)/(2piR *cosø) =time to be obtained/86400 "

Now plz identify my err
