₀^ 2 a f(x) f(x)+f(2 a-x) d x is equal to
Options
- Aa
- B-a
- C1
- D0
Correct answer
A. a
Step-by-step solution
Let I= ₀^ 2 a f(x) f(x)+f(2 a-x) d x...(i)I= ₀^ 2 a f(2 a-x) f(2 a-x)+f(x) d x...(ii) On adding Eqs. (i) and (ii), we get aligned 2 I & = ₀^ 2 a f(2 a-x)+f(x) f(2 a-x)+f(x) d x= ₀^ 2 a d x=2 a I & =a aligned
