Question

Sin2A /1-cos2A=_____________.​

Answer 1

Answer:

Solution:

[sin 2A/(1 + cos 2A)] [cos A/(1 + cos A)]

Using the formula cos 2x = 2 cos2x – 1 and sin 2x = 2 sin x cos x,

[(2 sin A cos A)/(2 cos2A)] [cos A/(1 + cos A)]

= sin A/(1 + cos A)

Using the formulas sin x = 2 sin(x/2) cos(x/2) and cos x = 2 cos2(x/2) – 1,

= [2 sin A/2 cos A/2]/ [2 cos2(A/2)]

= (sin A/2)/ (cos A/2)

= tan A/2
