I find it interesting that people advocate substitution ... in order to spot this you would need to spot that sec2 is the derivative of tan ... then if you spot that why don't you just see that it is tan3 with a bit of numerical adjustment

yeah I suppose, just easier to get the method marks with the other method?

But the integral here is (tan32x)/6 or am I missing something?
