00:00 Factor out 16
00:16 Take 1/16 outside the integral and rewrite x^2/16 as (x/4)^2
00:30 Substitution: u=x/4
00:37 Differentiate in both sides
00:47 Substitute x/4 and dx
01:08 Take 4 outside the integral
01:19 Simplify 4/16 and integrate 1/(1+u^2)
01:26 Undo substitution: u in terms of x
01:35 Add integration constant +C
01:42 Final answer!

Thank you for your video, why do we need to make the subsitution u=x/4? Isn't the integral of 1/(1+(x/4)^2) equal to arctan(x/4)?

Hello Sir, Can we use the formula 1/(x^2 + a^2) = 1/a (tan^-1(x/a))? since 'a' is 4 here?

Hiii . firstt your channel helped me alot . I love to think fastly in math and become like you๐Ÿ˜…
Second can you please do the integral of (x+1)^2 / 2+x^2
And thank you in advance !!

Is this problem the same as

Integral dx
=
16 + x^2

?
