Question

Prove that: (1+sinA-cosA/1+sinA+cosA) = 1-cosA/1+cosA​

Answer 1

Answer:

not understanding question

Answer 2

hey you have missed the square at LHS which made question wrong

as it is

[1+SinA-CosA]²/[1+SinA+CosA]² =[1-cosA]/[1+cosA]

and the proof for this is

[1+Sin²A+Cos²A+2SinA-2SinACosA-2CosA]/

[1+Sin²A+Cos²A+2SinA+2SinACosA+2CosA]

[2+2SinA-2SinACosA-2CosA]/

[2+2SinA+2SinACosA+2CosA]

(1+SinA)(1-CosA)/(1+SinA)((1+CosA)

(1-cosA)/(1+CosA)
