`intdx/(sqrt(4-x^2)`=

prove that intdx/(sqrt(a^2-x^2))=sin^(-1)fracxa+C

intdx/(xsqrt(x-1))

Evaluate: intdx/sqrt (4-2x-2x^2)

intdx/(x^2sqrt(x^2-1))

intdx/(x+sqrt(x))

Evaluate intdx/sqrt (a^2-x^2)

Evaluate intdx/sqrt (1-2x-x^2)

Evaluate: intdx/(sqrt (1+x^2)sqrt (log(x+sqrt (1+x^2))))

intdx/(sqrt(x)(1+x^2)^(5/4))= (A) (2x)/(1+x^2)^(1/4)+c (B) (2sqrt(x))/(1+x^2)^(1/4)+c (C) (2sqrt(x))/(1+x^2)+c (D) none of these

intdx/(xsqrt(x^(2n)-a^(2n)))
