I know that this is equivalent to inverse tangent, but is that using a table?

use trigonometric substitution, you will arrive at the same conclusion.

you can always substitute... c in the denominator that x2 +25 can be reduced to y2+1just by putting x= 5y.... but also c that u can put x=5 * tan(theta) which would reduce the lower term to just 1 term i.e sec2(theta) and u can integrate very easily...

Using inverse tangent (aka arctan) is not considered using tables.
