When you integrate 1/1-u², why can't you just apply the 1/2aln(a+x/a-x) formula?

It was not easier to convert 1/cos(x) to sec(x) and obtain the direct integral which is ln(sec(x) + tan(x) + c

hie please cross check I think there is an error denominator should be 1-sinx and NOT sinx-1....double check the working again

du/(u²+1) it's the table integral already, why did you make its solution harder

The other solution is lnItan(x)+sec(x)I +c.

Why should environment engineer study maths for the entire graduation
Maths is again incorporated for the first year of post graduate civil engineering has become useless even computer students rely on environment science ?!
