फलनों का x के सापेक्ष समाकलन कीजिए - `(x-1)sqrt(x^(2)+x+1)` |
|
Answer» Correct Answer - `(1)/(3)(x^(2)+x+1)^(3//2)-(3)/(2)[((2x+1)/(4))sqrt((x^(2)+x+1))+(3)/(8)log{(x+(1)/(2))+sqrt((x^(2)+x+1))}]` `int(x-1)sqrt(x^(2)+x+1).dx` `=int[(1)/(2)(2x+1)-(3)/(2)]sqrt(x^(2)+x+1).dx` `=(1)/(2)int(2x+1)sqrt(x^(2)+x+1).dx -(3)/(2)intsqrt(x^(2)+x+1).dx` |
