## Jonask Group Title $\int _a^b \frac{dx}{y}$,where $y^2=ax^2+bx+c$ one year ago one year ago

1. experimentX Group Title

reduce y in to this from (px + q)^2 + r

where $y^2=ax^2+bx+c$

sry i meant y^2

4. experimentX Group Title

do the same .. it wouldn't make any difference

$1/a(x+b/2a)^2-b^2/4a+c/a 6. Jonask Group Title \[1/a(x+b/2a)^2-b^2/4a+c/a$

i tried a euclidian sub of t $t=y+x\sqrt a$

8. experimentX Group Title

yeah .. then substitute u = Sqrt(a)(x + b/x) should be of the form |dw:1362742001381:dw|

yeah to the first post or euclidean?

10. experimentX Group Title

??

do you agree with the sub of$t=y+x\sqrt{a}$

12. experimentX Group Title

where did you get that y ... there is no such y.

13. experimentX Group Title

check your equation again ... don't put that y there ... there is no y involved. I think you are confused.
