solve integrate x^(-1/2)sin x dx

Question

anonymous · Answer

$$\int\limits_{}^{}x ^{^{-1/2}}(\sin x )dx$$

lgbasallote · Answer

are you allowed to use integration by parts?

anonymous · Answer

ya allow by using any method..

lgbasallote · Answer

i think IPB is the only way though =)) are you familiar with LIATE? (a method on which you'll use as u and which as dv)

lalaly · Answer

this is not an elementary fnction,, so by parts wont work

lgbasallote · Answer

aww that's a downer :(

anonymous · Answer

i hv tried the intergrate by part but the power keep increase can't eliminate the intergral

lalaly · Answer

how far in integration methods have u got?

anonymous · Answer

i think three
1st by formular
2nd by parts
3rd by subtitution

lgbasallote · Answer

what about algebraic sub?

lalaly · Answer

are u sure u wrote the question right?

lgbasallote · Answer

wont algebraic sub work?

let u = $\sqrt x$
$u^2 = x$
2udu = dx

$\LARGE \int \frac{\sin (u^2) 2\cancel{u}du}{\cancel{u}}$

$\LARGE 2\int \sin (u^2) du$

anonymous · Answer

i just copy from my friend i dont know whether it is correct or nt

anonymous · Answer

thn can you solve the sin(x^2)??

lalaly · Answer

ok lg how can u solve sin(u^2)?

lgbasallote · Answer

i was hoping you can do it ~''~

lalaly · Answer

it cant be done using the methods hes taken

lalaly · Answer

recheck the question

lgbasallote · Answer

i wolframed it and a fresnel thingy came out...i think this is a syntax problem

anonymous · Answer
