Question

How to integrate 1/(3-x)^(1/2)

Answer 1

@Kuroten87 Hi ,
\(\Huge \mathcal{\text{Welcome To OpenStudy}\ddot\smile} \)

Did you try substitution u= 3-x ?

Answer 2

I actually tried subbing the square root of 3-x and finding x, then subbing that

Answer 3

So x would equal 3-u^2 and dx = -2udu

Answer 4

ok, now try, u= 3-x
(instead of sqrt (3-x))

Answer 5

Now I have negative integral of 1/(u^1/2)du

Answer 6

thats quite simple right ?
can you do it ?

Answer 7

Maybe if I stare at it long enough. Thanks:)

Answer 8

lol......let me give you a hint :
\(\large \dfrac{1}{x^n}=x^{-n}\)
and you have standard integration formula for x^n dx

Answer 9

and welcome ^_^

Answer 10

Lol oh yeah... Basic stuff. My bad.

Answer 11

no problem :)

Answer 12
