INTEGRATION Tough Problem Solvers Beware

Question

anonymous · Answer

what is the problem?

anonymous · Answer

$$\int\limits_{}^{}xsin^{-1 }1/2{({2a-x}/a)^{1/2}}$$

anonymous · Answer

you forgot dx:)

anonymous · Answer

doesnt matter

anonymous · Answer

u guys still know its integration !! :)

anonymous · Answer

well if you want to be ignored by people, making them think that you know nothing and actually just writing of the internet...

anonymous · Answer

I dont understand....this was my previous test problem

anonymous · Answer

I cudn't solve it....so I asked.....

anonymous · Answer

@fakeee what do u want me to do then??

kainui · Answer

Did you try doing integration by parts?

anonymous · Answer

I tried everything my friend

perl · Answer

it would be more legible if you used parentheses for the argument of inverse sine

perl · Answer

no he doesn't have to remove his question

anonymous · Answer

sure, good bye:)

anonymous · Answer

$$\int\limits_{}^{}xsin^{-1}((1/2){(2a-x/a)^{1/2}})$$

anonymous · Answer

@perl I hope this helps

perl · Answer

yes that helps :)

kainui · Answer

Check this, is this correct? I noticed you might have put your parenthesis wrong: $$\int\limits_{}^{}x \sin^{-1}{( \frac{\sqrt{(2a-x)/a}}{2}}) dx$$

kainui · Answer

specifically is it (2a-x)/a or 2a-(x/a)?

anonymous · Answer

YES YES

anonymous · Answer

I am sorry I can't put it properly...havent got the hang of this!!

anonymous · Answer

1st part

anonymous · Answer

Anyone??

kainui · Answer

Well there are two possible strategies, to pick either x or arcsin(...) as your two different possible choices for integration by parts. I suggest doing it both ways and see what happens. =)

anonymous · Answer

ok

anonymous · Answer

can u be a little bit more elaborate pls!
