Cheers for that!!

The reason i want to know is because i am preparing to study for the ATPLs.....Im reading the notes before i start.

The first few pages of nav start with convergency. I dont know if there are any questions on it,but i sure know it doesnt make sense to me and it seems absolutely irelavent to flying an aircraft

The other thing is- I know
Convergence= Change in Long x sin of the mean lat.

What is sine???

Someone told me this is Trigenometry.... I dont know anything about Trig!!

Edited coz i use bad language!!!
( Happy now SCROGGS? )
