Integration by parts

[@christypriyanka8359]

Hi i love the way you teach math, I would like to add how about using LIATE TO CHOOSE u being the earliest in LIATE, WHERE L log, I inverse, A Alegebra, t- trigno, e- expo

[@sbmathsyt5306]

Nicely organised video and great examples with clear explanation. Awesome!

[@cykachu9720]

at 10:03 why did u change the 2nd minus to a plus

[@tj9382]

I love the integration of lnx, this is part of what makes maths so beautiful.

[@notmamari]

nothing makes math beautiful😭

[@harinathmohanraj8245]

​@@notmamari you serious.

[@Rozhan_Fard]

nice explanation 🙏🏻🙏🏻Thank you Starfish Maths❤

[@gracefrimpong9553]

Thank you so much for your help, this really will let me pass in my exam

[@ireneokeke8162]

Please how did you have minus in your answer in example no 3?

[@yogendrayadav3669]

Thanks for the easy explanation

[@chandradixit5]

Perfect 👌 Teacher 👍👌👌

[@brenmclean]

If I switched the u and v', shouldn't I get the same answer? I got x^3/3 . cos x - x^4/12 . cos x +c

[@samwelkariuki3114]

Perfect teacher

[@carlosmunoz5178]

Thank you, Sophia!

Hi! Why do we plus the c in the end ? Shouldn’t it be a minus c?

[@DGQQ78]

c is just an arbitrary real number. As -c is also an arbitrary number, we can just rename this constant and call it c again (abuse of notation). In other words, the sign in front of c does not really matter. Similarly, if you find +2c, one could rename it c using an abuse of notation. NOTE: some instructors might be not accepting this abuse of notation, and use a different new letter (or same letter, but with an index to distinguish it from the original c). For example, one could write -2c=c_1. I prefer using the abuse of notation, because we would have an extra notational complication. NOTE2: However, in further problems with differential equations it might be important to keep track of the constants

I love your voice.

Madam You are such an excellent teacher you are really making me understand this staff, but my request is, I'm finding it difficult to understand how you integrating sin3x for it to become - 1/3cos(3x), especially the numbers, plz help me understand madam. Thanks

[@donpowers8726]

The antiderivative of sin is - cosine, then you need to deal with the inside derivative 3x

Thank you so much Mam🌟

Are u a teacher for year 10 to 11s?

[@armstrongtixid6873]

Y10-11 is usually more oriented at GCSE for the average student. This would be more AS/A Level which is Y12-13 for the average student. So if she were a teacher, she'd *probably* teach Y12 and 13. However, if you excel in Maths, you may do integration in Y11 or perhaps Y10. I know some people who learnt in Y8 and 9.
