A FAST WAY TO REPEATED INTEGRATIONS BY PARTS - EFFICIENT AND POPULAR APPROACH

I absolutely love integrals and this channel provides great content!

Wonderful to hear that. Thank you so much for the comment…!

Tabular Method

[@gayansamarasekara]

Correct. Also called the DI method.

Tabular Integration or the so-called D-I method does the job straight away. I learnt it from Blackpenredpen channel.

[@gayansamarasekara]

Of course. Glad to hear you already knew the method. Thanks for the comment.

Whats the answer to the hw question? I want to know if I understood method correctly

[@gayansamarasekara]

Thanks for your question. Right now, I’m working on something, I’ll get back to you tomorrow. Sorry about the delaying. If you paid attention to the changing + / - signs of the integrals (because sine/ cosine repeated integration leads to alternating signs), along with the method specific changes of + / - signs, your answer should be correct, provided you followed differentiation and integration in each step correctly.
