How do i solve this? I arranged the problem to look like: 1/(x^2+1)dx

How do I solve for C*

>I don't know where to plug in x(pi/4) = 1
when t = pi/4, x(t) = 1
substitute those two numbers into

you already posted this in the /sci/ stupid questions thread and apparently didn't read any of the help you got

The x(pi/4) = 1 seems kind of weird. Can you post some of the other problems so I see if they are the same?

how is that at all weird
x is a function of t
it's the same shit as the f(3) = 7 shit you were doing in high school just with different symbols

if thats the case just substitute x=1 t=pi/4 and rearrange for c, then take the arctan over to get x=tan(4t+c)
