just confused on a couple problems, not sure how some of the numbers showed up in the answer
The answer is 1/3 LN| t^3+6t+3| +c
Where did the natural log come from, is there any type of formula I am missing for this? That's the only part I'm confused about from the problem.
2.) defined between 3 and -2
The answer is 35/6. For my math, I did the following:
and then plugged in the defined points, (3) - (-2), however I'm not getting anything close to 35/6.
Any tips and advice is appreciated, also if you have any special formulas that you use to solve definite integrals would also be nice,
