int2^(n)dn

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

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

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

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

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

int (cos n-sin n)/(cos n+sin n)dn

I=int(sinn)/((1-cos n)^(2))dn

Q.prove that int(e^(n+(1)/(n))+n(1-(1)/(n^(2)))*e^(n+(1)/(n)))dn=n*e^(n+(1)/(n))+C

If (n^(2)-1) be one of the factors of the polynomial f(n)=an^(4)+bn^(3)+cn^(2)+dn+e , then

If R is a relation on a finite set having n elements,then the number of relations on A is 2^(n) b.2^(n)^^2 c.n^(2) d.n^(n)
