00:00 Rewrite expression
00:31 Substitution: u=sqrt(x)
00:37 Differentiate in both sides
00:43 Substitute sqrt(x), x and (1/2sqrt(x))dx
01:14 Substitution: u=sin(t)
01:24 Differentiate in both sides
01:32 Substitute u, u^2 and du
01:57 Apply 1=sin^2(t)+cos^2(t)
02:42 Simplify expression
03:01 Apply 1=sin^2(t)+cos^2(t)
03:19 Apply a^2-b^2 = (a+b)(a-b)
03:57 Simplify expression
04:15 Integrate 1 and sin(t)
04:28 Undo substitution: t in terms of u
04:52 Simplify expression
05:16 Undo substitution: u in terms of x
05:27 Add integration constant +C
05:37 Final answer!
