Thread: seperation of variables help

use seperation of variables

y' = (t^2)*e^(y+2t)


i got the answer of y(t) = (t^3)/3-2t+c

but online it tells me its wrong =(
what am i doing wrong??

on another note i dont even know how to start this one:

Not sure how you got your answer but separating gives



For the second

.

ok i got

tan y =1/t + C

from there i take the arctan(1/t + C)???
im really frustrated and am never to finish a problem off i hate this feeling =(
thank you for your patience with me

You'll need to integrate the right hand side. You differentiated.
