`int(dx)/(x^(2)+2x+2)`

Assertion (A) : int(dx)/(x^(2) + 2x + 3) = (1)/(sqrt(2)) tan^(-1)((x+1)/(sqrt(2))) + c Reason (R) : int(dx)/(x^(2) + a^(2)) = (1)/(a) tan^(-1)((x)/(a)) + c

int(dx)/(2x^(2)-x)=

What is int(dx)/(2x^(2)-2x+1) equal to ?

int_(-1)^(0) (dx)/(x^(2) + 2x + 2 ) is equal to

What is the value of int(dx)/((x^(2) + a^(2)) (x^(2) + b^(2))) ?

"If" int(dx)/((x^(2)-2x+10)^(2))=A("tan"^(-1)((x-1)/(3))+(f(x))/(x^(2)-2x+10))+C ,where, C is a constant of integration, then

int(2x)/(1-x^(2))dx

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