13. Tushara

14. Tushara

some1 plz check my working, i hope its right

15. marcoduuuh

Wow, thanks so much for all that! @Tushara

16. AravindG

@Tushara It would have been a better idea if you helped her get to the solution instead of posting worked out answer like that .

17. AravindG

refer openstudy COC http://openstudy.com/code-of-conduct

18. Tushara

im pretty bad at getting some1 to work through the problem... i shud try that, thnx for the advice aravind.... and np marcoduh, make sure u understand every step

19. marcoduuuh

She worked through it though, it means when you just give out the answer. When you just give the answer that doesn't help but when you work through it that helps because I can see how to do it. (:

20. AravindG

@marcoduuuh as she said make sure you understand every step ..if theres doubt ask :)

21. marcoduuuh

Thanks!

22. AravindG

maybe thats the case here ,but there is high chance that students misuse this facility for getting their homework done.that is why Openstudy wants helpers to "guide"the asker to the solution , giving them a feeling that they did it themselves

23. marcoduuuh

I totally understand that! I mean, if you just give the answer it won't help because it's not showing how to do it but for me, this helped me because it was shown how it was done so I can apply it to my future.

24. AravindG

I do get your point ..but imagine someone who came here for submitting their worked out homework ...this worked out answer would have been a lottery for them

25. marcoduuuh

But I do understand what you're trying to say.

26. marcoduuuh

Yeah! I gotcha!

27. AravindG

:) nice ..happy openstudying

28. marcoduuuh

Thank you so much. (:
