1. ## Improper Integral/Limits

I am pretty bad with these two topics, help would be appreciated as I tried for hours.

from 0 to 1 (dx/x^.4)

limx0+ (9sin(x)ln(x))

2. Hello,

Note that .4=2/5

So you have $\int_0^1 x^{-2/5} dx=[\frac{5}{3} x^{3/5}]_0^1 = \frac{5}{3}$

For the second one, perhaps you can say that when x is near 0, sin(x) ~ x

And limit of x ln(x) when x tends to 0 is 0.

3. ohhh Okay, well i got the first one right, i guess the answer in the back was wrong, no wonder i kept getting it wrong.
