`int (n^(2)-n^(3))dn`

int sqrt(a^(2)-n^(2))dn

If I_(n)=int(a^(2)+x^(2))^((n)/(2))dx, then show that I_(n)=((x(a^(2)+x^(2))^((n)/(2)))/(n+1))+(na^(2))/(n+1)I(n-2)

I=int(n^2dn)/(sqrt(a^(3)-n^(3)))

int(n)/(sqrt(n-3))dn

int_ (2) ^ (3) (n) / (1 + n ^ (2)) dn

int(n^(4))/((n-1)(n^(2)+1))dn

int_(n)^(n+1)f(x)dx=n^(2)+n then int_(-1)^(1)f(x)dx=
