Ok so my textbook explains all the rules to carry the inherent uncertainty in measurements through mathematic calculations (the result of an addition must have as many decimal places as the term with the least decimal places, etc, it also explains significant figures etc...) and at the very end...

Hey guys, searching around the web I found an explanation from MIT for this very same integral, here it is...

∫(tanxsec^{2}x)dx <---Original function to integrate. I do: ∫(tanxsec^{2}x)dx ---> ∫(tanx\frac{1}{cos^{2}x})dx ---> ∫((\frac{sinx}{cosx})(\frac{1}{cos^{2}x}))dx ---> ∫(\frac{sinx}{cos^{3}x})dx ---> substitution: [t=cosx , dt=-sinxdx -> [itex]\frac{dt}{-sinx}[/itex]=dx] --->...

*SOLVED* Indefinite integrals. Arriving at different results. Mistake found. Thanks!, everything looks correct now.
