Page 1: Advanced Integration Techniques

This page covers two main integration techniques: partial fractions and integration by parts, along with the tabular integration method.

Integrating Using Linear Partial Fractions

The section begins by explaining the use of algebraic methods to transform integrands.

Definition: Partial fractions rewrite a rational integrand as a sum of rational functions with linear functions in each denominator.

This method is used for quotients of polynomials when the denominator can be factored into linear and non-repeating factors.

Example: An example is provided for integrating 3x2+4x+13x² + 4x + 1 / x2+5x+6x² + 5x + 6 dx, demonstrating the step-by-step process of partial fraction decomposition.

Integration by Parts

This section introduces integration by parts as a method to transform integrals into more easily computable forms.

Highlight: The technique is based on the product rule of differentiation.

The general formula for integration by parts is provided: ∫u dv = uv - ∫v du.

Vocabulary: LIATE - An acronym for choosing 'u' in integration by parts, standing for Logarithm, Inverse Trig, Algebraic, Trigonometric, Exponential.

Several examples are given to illustrate the application of integration by parts, including integrals involving trigonometric and logarithmic functions.

Tabular Integration

The page concludes with an introduction to tabular integration, a method for efficiently performing repeated integration by parts.

Definition: Tabular integration is a technique that integrates repeatedly without several steps, using a table format.

An example is provided to demonstrate the tabular method for integrating x² e^x.

The document emphasizes that these integration techniques can be applied to both definite and indefinite integrals, and may be used with literal functions presented in tabular form.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
