13) If `(x+1)/(x^(2)(x+2))=(A)/(x)+(B)/(x^(2))+(C)/(x^(3))+(D)/(x^(4))+(E)/(x+2)` then B+D+E=

If (1)/(x^(4)+x^(2)+1)=(Ax+B)/(x^(2)+x+1)+(Cx+D)/(x^(2)-x+1) then C+D

If (1)/(x^(4)+x^(2)+1)=(Ax+B)/(x^(2)+x+1)+(Cx+D)/(x^(2)-x+1) then C+D=

(if^(4)-3x+3)/((x-1)^(3))=Ax+B+(C)/(x-1)+(D)/((x-1)^(2))+(E)/((x-1)^(3)) then

If x/((2x-1)(x+2)(x-3))=A+B/(2x-1)+C/(x+2)+D/(x-3) then A=

Integrate w.r.t x,x log x(A)(1)/(4)x^(2)log((x^(2))/(e))+k(B)(1)/(2)x^(2)log((x^(2))/(e))+k (C) (1)/(4)x^(2)log((x)/(e))+k(D) NONE

(d)/(dx)[log{e^(x)((x-2)/(x+2))^(3/4)}] equals (x^(2)-1)/(x^(2)-4) (b) 1 (c) (x^(2)+1)/(x^(2)-4) (d) e^(x)(x^(2)-1)/(x^(2)-4)

Choose the correct answer int x^(2)e^(x^(3))dx equals (A) (1)/(3)e^(x^(3))+C(B)(1)/(3)e^(x^(2))+C(C)(1)/(2)e^(x^(3))+C(D)(1)/(2)e^(x^(2))+C

int e^(x^(4))(x+x^(3)+2x^(5))e^(x^(2))*dx is equal to a.(1)/(2)xe^(x^(2))e^(x^(4))+c b.(1)/(2)x^(2)e^(x^(4))+c c.(1)/(2)e^(x^(2))e^(x^(4))+cd(1)/(2)x^(2)e^(x^(2))e^(x^(4))+c

(xe^x)/(1+x)^2dx= (A) e^x/(1+x) (B) e^x/(1+x)^2 (C) e^xlog(1+x) (D) none of these

(x)/(x-1)+(1)/(x+1)+(2x)/(1-x^(2))=?( a) 1 (b) 2 (c) 3(d)4
