Integral of a quadratic function (KristaKingMath)

► My Integrals course: https://www.kristakingmath.com/integr... Learn how to calculate the integral of a quadratic function by completing the square. To complete this problem, you'll need to complete the square of the quadratic, then use trigonometric substitution to calculate the integral. Once you've used trigonometric substitution to simplify the integral, you'll use integration by parts to simplify further. Finally, you'll back substitute to get the answer in terms of x instead of theta. In order to do this, you'll need to use the values from the right triangle you drew when you set up your trigonometric substitution problem. ● ● ● GET EXTRA HELP ● ● ● If you could use some extra help with your math class, then check out Krista’s website // http://www.kristakingmath.com ● ● ● CONNECT WITH KRISTA ● ● ● Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;) Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!” So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.
