int x(1-x)^(23)dx

int(x^2)/(sqrt(1-x))\ dx (ii) intx(1-x)^(23)\ dx

int_(7)^(23)(dx)/((x-2)sqrt(x+2))=(1)/(2)log.(15)/(7)

int (dx)/(x^(2)+x+1)dx is :

(i) int ((1+x)^(3))/(sqrt(x))dx " "(ii) int((1+x)^(3))/(x^(4)) dx

(i) int ((1+x)^(3))/(sqrt(x))dx " "(ii) int((1+x)^(3))/(x^(4)) dx

(i)int(x^(3)-1)/(x^(2))dx(ii)int(x^(2/3)+1)dx

Evaluate the following integrals: (i) int 2x sqrt(1 + x^2)dx " " (ii) int e^(-x^2) x dx " " (iii) int (sin x)/(1 + cos x) dx (iv) int 1/(1 + x^2)dx " " (v) int x (a - x)^8 dx .

int(e^(x))/((1+x)^(3))dx-int(e^(x))/(2(1+x)^(2))dx=
