To learn how to format math in textual form, please try here. For now, is the following what you meant?

. . . . .$\displaystyle{\int_0^{\frac{1}{2}}\, \frac{4}{1\, +\, 4t^2}\, dt$

If not, please reply with corrections. If so, please reply with confirmation, and provide a clear listing of your efforts so far, such as what inverse-trig derivative you tried to apply, or whatever other method you have attempted. Thank you!

We don't do online classes here. If you don't remember enough to know where to get started (like "integration" or "inverse-trig" stuff like they said in the other answer) then you probably need to hire somebody who can spend the next month or so teaching you last year's stuff again. Otherwise use your book and your notes and online stuff like here, here or here.
