can you please type this out in latex? just put $$\text{$}$$ before the equation and $$\text{$}$$ after the equation. Integral is \int. integral from a to b is int_a^b. You can use the equation editor as well if you don't know latex.

$int \[1\div1+x^2+y^2 dy$

3. richyw Group Title

uh, try again. are you trying to say $\int\left(\frac{1}{a}+x^2+y^2\right)dy$

4. chakshu Group Title

yup, starting from the equation above... $\int\frac{1}{a}dy+\int x^2 dy+\int y^2 dy$$\frac{1}{a}\int dy+x^2\int dy+\int y^2 dy$then do these basic integrations,$\frac{1}{a}y+x^2y+\frac{y^3}{3}$and finally, factoring out the $$y$$ we have,$y\left(\frac{1}{a}+x^2+\frac{y^2}{3}\right)$
