[@felistusmbewe5274]

Thank you very much Mr sichamba, I wrote this year's gce math and I cleared, thanks for your help I use to follow your videos and they really helped me, continue doing your best

[@user-yr7td3rc6p]

What's a difference between distance in notical miles and kilometers

[@LovenessNyambe-kw8vz]

I like the way you teach it's clear and understandable

The distance formula used was for calculating points lying along the same longitude

[@michealmwamba-pd2jp]

My concern is on LK, Why using the formula for longitude instead of latitude,,,,2πRcosx

[@JuniorMaseka]

Yeah, I also noticed that

[@edsonmuwowo7458]

My concern too

[@petermtonga2239]

You're right. LK makes distance along the same line of latitudes.

[@CeciliaKabunda-dw6gq]

Where are you getting 15

[@NarteyEunice]

Modular

[@benwillson8330]

Last question is wrong though. L and k Use small r

[@PurestoneMwansa-bc9oo]
