Should have seem me try taking a high school Physics class not even knowing what sin,cos,tan even were(!). So much for calculating force vectors and such. I understood the theory, but had no hope without enough math classes to do the assignments. I did one problem with a fraction under a radical sign backwards once because that was the only way I could use my weak Basic Algebra skills to even deal with it; took 5 hours to do it. Teacher later re-did the work I turned in, and very politely concluded that somehow all my mistakes canceled out and I got the answer right(!) Teacher was great, once he knew how hopeless my math skills were, he went to Guidance, and told them to move me into Study Hall, because all I was doing is failing, and asked them why they ever let me sign up for Physics anyway?! There are some odd things I can do, like take 10% of a number in my head, but for the love of Sir Charles Babbage, don't ask me to show my work, because I can't do it. I also got rather good at geometry proofs in Basic Geometry for some odd reason.

It's really misleading to use a trig sub! Misleading also to say that x^2-8x+1 can't be factorized! x^2-8x+1 = (x-a)(x-b) where a = 4+sqrt(15) & b = 4-sqrt(15). Then anti-derivative is (1/k).ln[(x-a)/(x-b)] where k = a-b = 2sqrt(15). Much simpler ... and no trig! Moreover, checking the result by differentiation is a nightmare using Prof. Breiner's method. Just try it! Differentiating ln[(x-a)/(x-b)] gives (by chain & quotient rules) (a-b)/[(x-a)(x-b)] and the checking is done. Regretfully, the method shown in the video demonstrates 'hammering' rather than 'understanding'.

I admire you.I was bad in maths at school.Really bad.God, i didnt like it at all.My teachers also disliked me.I passed all the grades and years.Never had to retake a year at school but it was really heavy for me.That blackboard , full of logaritms, and other stuff in high school.Didnt remember much, after.Today, you ask me something of that and i woud have to study again.Why was i like that?.

In Calculus, this is where each student algebraic skills have to be really good in order to solve these types of problems with mathematical tricks. In order to excel in mathematics , students must know algebra from top to bottom. Professor Breiner demonstration of Integration by completing the square is one of the techniques of integration.
