Answer 3

I'm supposed to do this by parts, but I don't see how I can do it by parts.

Answer 4

If you click the link, there is the option to show steps

Answer 5

\[u=\arctan4t\]

Answer 6

\[dv=dt\]

Answer 7

\[du=(4dt)/(1+16t^2)\] \[v=t\]

Answer 8

Yes, do this by parts, do you know formula?

Answer 9

\[\int\limits(\arctan4t)dt=t*arctan4t-\int\limits((4t)/(1+16t^2))dt\]

Answer 10

4t drops to zero after a few cycles thru the parts
