So, I'm gearing up for a final exam her, and while I handled learning the integration of trig,log and exponential functions...
Nowthat I've got a good grasp of all these rules I'm getting lost in the sheer vastness of what I need to be aware of...
For example, how do you, in general distinguish between the different ways to swap x for du and u? I mean, sometimes you will see sweeping out the x, sometimes the ax, sometimes the x2^2-a, or other times you will swap the whole trig function, other times it takes just the expression within (the angle).
So, how does one distinguish?
On the same note, how do we decide the difference between inverse trig, general power and log rules?
As far as this all goes, I understand the rules, but in the vastness of possibilities I find my use o these things approaching chance.
