Thank you so much... Could you please clarify how to decide whether to use cos, or sin or tan
it depends on ......of which 2 sides we have to find the relation in right angled triangle
we always take the side opposite to the choosen angle as perpendicular.....and the side attached to the angle as base
when finding relation between Hypotenuse (H) and Perpendicular ( P), we use sin............. i.e.
sin x = h/p
opps it's....p/h
similarly.....cos x = b/h
tan x = p/b
