int 1/(sqrt(x + 1) + sqrt(x - 1)) dx = f(x) এবং f(1) = 0 হলে, f(x) =?
A. 1/3 [(x + 1) ^ (3/2) + (x - 1) ^ (3/2)] + c
B. 1/3 [(x + 1) ^ (3/2) - (x - 1) ^ (3/2)] + c
C. 1/3 * [(x + 1) ^ (3/2) - (x - 1) ^ (3/2)] - (2 ^ (3/2))/3
D. 1/3 * [(x + 1) ^ (3/2) + (x - 1) ^ (3/2)] + (2 ^ (3/2))/3
সঠিক উত্তরঃ
B.
1/3 [(x + 1) ^ (3/2) - (x - 1) ^ (3/2)] + c
