(1)∫(sec1/x)^2/x^2dx
= -∫(sec1/x)^2d(1/谨友笑x)
= -tan(1/x) + C
(2)∫(e^2x-1)/e^xdx
= ∫(e^x - e^-x)dx
= e^x + e^-x + C
(3)∫e^x(1+e^x)dx
=∫(e^x + e^2x)dx
= e^x +1/祥含2e^2x + C
(4)∫√arcsinx/(1-x^2)dx
=∫告轮(arcsinx)^(1/2)darcsinx
=2/3(arcsinx)^(3/2) + C
= -∫(sec1/x)^2d(1/谨友笑x)
= -tan(1/x) + C
(2)∫(e^2x-1)/e^xdx
= ∫(e^x - e^-x)dx
= e^x + e^-x + C
(3)∫e^x(1+e^x)dx
