Answer:
Step-by-step explanation:
SInA/SecA+TanA - 1 + CosA/CosecA+CotA - 1
= SinA/1/CosA + SinA/CosA - 1 + CosA/1/SinA + CosA/SinA - 1
= SinACosA/1+SinA - CosA + SinACosA/1 + CosA - SinA
= SinACosA[1 /1 + (SinA-CosA) + 1/1 - (SinA-CosA)]
= SinACosA[1 - (SinA-CosA) + 1 + (SinA-CosA) / 1 - (SinA-CosA)²]
= 2SinACosA/1 - Sin²A - Cos²A+ 2SinACosA
= 2SinACosA/Cos²A-Cos²A+ 2SinACosA
= 2SinACosA/2SinACosA
= 1
= R.H.S
Hence Proved.
