Walk me through the steps, please:?

Integrate: dy/(y Sqrt 4y^2-1) with lower limit of -1 and upper limit of -Sqrt 2/2

Thanks.

Substitute y = 1/t.

Then

dy = -dt/t^2

and t varies from -1 to -sqrt(2).

You get:

-\int_{-1}^{-sqrt(2)} dt/[t^2(1/t)sqrt((4/t^2)-1)]

which simplifies to

\int_{-1}^{-sqrt(2)} dt/sqrt(4-t^2)

= [asin(t/2)]_{-1}^{-sqrt(2)}

= asin(-sqrt(2)/2)-asin(-1/2)

= -pi/4 + pi/6

= pi/12
