Integral of cot(x) with u-substitution | Calculus 1 Exercises

Показать описание
We evaluate the indefinite integral of cotx using u-substitution and the fact that cotangent(x)=cosx/sinx. Letting u=sin(x) will turn this into a straightforward integral. The integral of cotangent, it turns out, is the natural log of sin(x) plus C! #Calculus1 #apcalculus

I apologize for wearing a tanktop in a math lesson, this is far more informal dress than I'd prefer. Please forgive me on this matter, as the heat has grown so intense that the only alternative I can contemplate is to wear nothing at all. Where the video cuts, I wipe sweat from my brow and gasp for air, when the camera is off, I peel my body from my chair and rush to turn my fans and AC back on, then dry the puddles of sweat that have accumulated on my desk. Forgive me.

What a great video, I'm learning graph theory for my undergraduate thesis, but I have some problem with paired domination number and upper bound on paired domination number(the gamma of upper bound and gamma the minimum cardinality). I could not get the exact example cause lack of journal that explain and give the example of them. Would you mind if you make a explanation video about these problem? thankyou

I just assumed your tuxedo was at the dry cleaner's.
