Hii There,

Derivatives do not care about constant terms, whereas integration takes them into account. Integration involves considering constant terms, and occasionally, it's necessary to determine their values. Therefore, I recommend completing the study of Applications of Derivatives (AOD) first, and then moving on to indefinite and definite integration. I'm confident that you'll find the integration process more manageable and comprehensible by doing so.

I hope this answers your question.

Thanks
