(i) int (3x^2)/(x^6+1) dx (ii) int (3x)/(1+2x^4) dx

Evaluate : int(x^(2)+3x-1)/(2x)dx

(3) int(x^(2)-5x+6)/(x-3)dx

int (3x^2+6) dx

int(3x^(2))/(x^(6)+1)dx

int(x^(2))/(1+x^(6)) dx

(i) int_1^3 (3x)/(9x^2-1) dx (ii) int_2^3 x/(x^2+1) dx

int (1+3x^2)/(x(1+x^2)) dx

int ( x +2)/( 2x ^(2) + 6x + 5) dx = p int ( 4x +6)/( 2x ^(2) + 6x +5) dx + (1)/(2) int (1)/( 2x ^(2) + 6x + 5) dx then p
