    Wow, thank you so much again! Do you have any tips on how to know if your answer is right on the exam? Like, I obviously won't have the actual answer in the exam to check my answer, so how do I know if my answer is the actual answer?

    do you have a calculator that can do numerical integration?
    I usually just use my calculator to integrate the expression between 0 and 1 (or some other domain) and see what answer I get. I then put in the same limits for my answer. if they're the same then I'm pretty sure I've integrated correctly. does this make sense? I can go through an example if you want

    let's say I want to integrate x (silly I know but it works as an example). I do some integration and think it's x²/3. so I go on my calculator and integrate x between 0 and 1 which would give me ½. but if I put in the limits 0 and 1 into my answer (x²/3) I would get ⅓ which isn't the same answer, so I know I've gone wrong somewhere. make sense?
