2. β«u^n du = (1/(n+1))u^(n+1) + C, n β  -1
3. β«(1/u) du = ln|u| + C
4. β«e^u du = e^u + C
5. β«a^u du = ((a^u)/ln a) + C
6. β«sin u du = -cos u + C
7. β«cos u du = sin u + C
8. β«sec^2 u du = tan u + C
9. β«csc^2 u du = -cot u + C
10. β«sec u β’ tan u du = sec u + C
11. β«csc u β’ cot u du = - csc u + C
12. β«tan u du = -ln|cos u| + C
13. β«cot u du = ln|sin u| + C
14. β«sec u du = ln|sec u + tan u| + C
15. β«csc u du = ln|csc u - cot u| + C

Hi. Is it possible you could add some explanation to your post? It's just a list you've copied from a book!

But indeed the goal is to provide a formula for convenience. Look at the title! "Some Integral Formulas". ππππππππππ If you want to see with an explanation, it's in my other post, with the title (with proof)
