Answer 1

$intlimits { (frac{1}{x} + frac{1}{x^3} )} , dx = intlimits { (frac{1}{x} + x^{-3})} , dx = lnx- frac{1}{2x^2} +c \ intlimits {(x-2e^x)} , dx = frac{x^2}{2} -2e^x+c \ intlimits { (frac{x^4-2x^3+3x^2}{x^2}) } , dx = intlimits { (frac{x^2(x^2-2x+3)}{x^2}) } , dx = intlimits {(x^2-2x+3)} , dx = \ = frac{x^3}{3} -x^2+3x+c$
$intlimits {( frac{cos^2x+sin^2x}{cos^2xsin^2x}) } , dx = intlimits ({ frac{1}{cos^2xsin^2x}) } , dx = intlimits { frac{2}{sin^22x} } , dx = -ctg2x+c \ intlimits {(1- frac{1}{x^2} )} , dx = intlimits {(1-x^{-2})} , dx = x+ frac{1}{x} +c \ intlimits {((6x^2+3)*(x+2))} , dx = intlimits {(6x^3+12x^2+3x+6)} , dx = \ = frac{3x^4}{2} + 4x^3 + frac{3x^2}{2} + 6x+c$
