Web bonus problem--Week 3

**Victor Ivrii**:

When I wrote "type" I meant type on forum. Like I do:

$$y'+2\cot(t)y=\cos(t)$$,

then

$$I=\exp\Bigl(2\cot(t)\,dt\Bigr)=\exp \bigl(2\ln \sin(t)\bigr)=\sin^2(t)$$

and so on, not to put image (even typed) on forum.

Don't cut lines too short... Also $\exp $, $\cos$ etc should be upright (in $\LaTeX$ it is \exp, \cos).

No external images! Post attachments

**Victor Ivrii**:

Usually web bonus is given to the first poster (or may be for improvements if the first poster did not get everything right). This time I was more generous. But not infinitely. Bonus got first 5 or so
