Web bonus problem--Week 3

<< < (10/10)

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
