Simplify sin 2 y / (1 - cos y) Simplify sin2y / (1 - cos y)
Simplify
sin2y / (1 - cos y)
plz check this : (sin2 y)/(1-cos y)=(1-cos2 y)/(1-cos y) = (12 - cos2y)/(1-cos y) = (1 + cos y) = 1 + cos y = ans.
plz check this :
(sin2 y)/(1-cos y)=(1-cos2 y)/(1-cos y) = (12 - cos2y)/(1-cos y) = (1 + cos y) = 1 + cos y = ans.
