I'm doing the OCR MEI AS Mathematics specification. Integration is part of Core 2 (C2). This is a question I'm stuck on for homework, which involves using negative and fractional indices in integration. Any help would be really appreciated!
I'm on AQA but hopefully my method is okay, and hopefully my integrating skills and general calculations are good!
It will integrate to-3x^-1+2x^-4
You then need put 2 and 1 into it, subtracting one from 2. If that makes sense. And I came out with the answer of -3/8 but I'm not sure if that's correct or not! I did do the workings out on paper and take a picture but I'm not sure how to put thatt on here for you with out putting it as a resource!
Thanks, this was really helpful! It was good to see it all laid out step-by-step... It looks so simple and straightforward now! The question is multiple choice and one of the answers was -3/8 so I think you're probably right :-)
