question:$\displaystyle \int_{-\infty}^{-1} \frac{1}{\sqrt{2-w}}dw$

work:$\displaystyle \lim_{t\to-\infty}\int_t^{-1}\frac{1}{\sqrt{2-w}} \, dw$ I used u substitution with $\displaystyle u=2-w$ leaving me with $\displaystyle \lim_{t\to-\infty}2\sqrt{2-w}$ from -1 to t

answer: diverges. Sorry, delete this post
