is that right sorry couldnt think of a better way

6. incomplte

Looks good to me

7. sat_chen

last problem before im done for the week so can someone else verify ty

8. sat_chen

not that i dont respect you incompite :P

You could of separated it from the beginning first: $\int\limits \frac{ \sec^2(x) }{ \tan^2(x) }dx - \int\limits \frac{ 1 }{ \tan^2(x) }dx$ use u-substitution: u = tan(x) du = sec^2(x) $\int\limits \frac{ 1 }{ u^2 }du - \int\limits \frac{ 1 }{ \tan^2(x) }dx$ and you know: $\frac{ 1 }{ \tan^2(x) }= \frac{ 1 }{ \frac{ \sin^2(x) }{ \cos^2(x) } } = \frac{ \cos^2(x) }{ \sin^2(x) }= \cot^2(x)$ proceed: $\int\limits \cot^2(x)dx = -x-\cot(x)+C$ PUT EVERYTHING TOGETHER: $-\frac{ 1 }{ \tan(x) }-(-x-\cot(x))+C$

You got the questions wrong @abb0t . Its tan/sec not the other way around

11. sat_chen

you did the question wrong

12. abb0t

omg. Lol. fudge.

13. sat_chen

well sorry for making you waste so much time :(

14. sat_chen

so was i right abb0t

15. sat_chen

i feel really bad for making you take so long and you got the question wrong really sorry next time ill make iit more clear :(

16. incomplte

lol im pretty sure it is

17. abb0t

mmk.

18. incomplte

The int of sec^2 is tan. You dont need any other steps to compute that.

19. sat_chen

the sec^2x cancel out leaving 2/sec^2x which is 2ln(tanx) right

20. incomplte

you cant just throw the 1 away. Its 1, not 0

21. abb0t

am i looking @ the wrong question?! LOL

22. sat_chen

|dw:1359159907953:dw|

23. sat_chen

heres the question again

24. sat_chen

yea i do believe its right ty guys i feel bad for ab0t all that work :(

25. incomplte

If your professors says its wrong, request to see where they got their degree from lol

26. sat_chen

my professor is a smart dude hes got masters at 21 so ill believe him if he says im wrong XD

27. abb0t

lol. whoa watch out, we got a bada_ _!! JK he's human and still susceptible to mistakes.

28. incomplte

Well im 4 months away too, in electrical engineering to be precise.

29. sat_chen

me too woot

30. sat_chen

im also ece

31. sat_chen

but im second year 19 so if i try hard enough i may get done by 21

32. abb0t

33. sat_chen

avoided math as much as i could :P

34. incomplte

hahahhaa

35. sat_chen

yea right abo0t

36. incomplte

You prolly still have to take diffe eq, multi variate and statistics then. Good luck lol

37. abb0t

Don't forget Linear Algebra.

38. incomplte

So smart for someone who is in 8th grade

39. sat_chen

yea i do and i hate math so not the best major for me XD

40. sat_chen

41. sat_chen

hest that dude right there

42. abb0t

omg. lol. i was guessing. geezbus. Lol

43. incomplte

Dont give up though, the degree is hot cake once you graduate. I promise

44. sat_chen

i know thats why im keeping at it

45. sat_chen

and i know some people that got direct to intel from here for 100k + so im gonna work my retriceoff

46. sat_chen

butt off*

47. sat_chen

and hes 21 as well so should be a good life from then on :P

48. incomplte

And that youtube guy is on a whole different level. As long as he can spit off derivatives and int from his head when he turns 18, otherwise he will be that one yotube guy

49. sat_chen

that was just a quick google search btw so im sure there are more genious of abb0t level ;)

50. incomplte

haha bye all

51. sat_chen

u in us by the way
