So looking at our square root, we see that we have the form of, we have x squared minus 9.
00:09
So that's of the form x is equal to 9 is 3 squared.
00:16
So that's 3 secanths of beta.
00:20
And now taking our derivative, that's equal to 3 derivative of sequence is secant tangents.
00:32
Okay, so let's rewrite what we have.
00:34
So we have the integral x is 3 ccant.
00:37
So that's nine secanth square theta over the square roots of x squared so that's nine secence square theta minus nine we can factor out of nine and then we also have three secence theta theta ttta for d x so we can rewrite this as in a row of nine times three secence squared data, sequence of theta, tangents of data, and d data.
01:12
And now we pull out that 9, or the square root of 9, which is 3.
01:17
And then we have the square root of secund squared minus 1, which is tangent squared data...
