This is a really simple integral on an online practice site, but the computer says my answer is incorrect. I re-checked my solution with derivatives and think that it is right. Can anyone help out?
My solution is 6.4x^5/2 + 6.6x^5/3 + C.
Thank you for the verification, guys. I'll let my professor know that the website is incorrect.
I entered my answer as a radical and it still says that it is incorrect. I don't know if there is a problem with the web site, but it also says that my answer to this question is incorrect:
My answer to this definite integral was 54/63 + 140/63 = 194/63. Is this also a website issue?
This time your answer is incorrect. It should be, http://wims.unice.fr/wims/wims.cgi?s...on=12&format=t
Hope this will help you.
Thanks for the checks Sudharaka. I accidentally copied my answer over to the post incorrectly and I edited it soon after I posted it (but I guess you were still responding to the original post). I notified my professor about the errors, so I guess that's all I can do.
