but then why didnt the person put 1325/2 in the problem?

like how did he get the 3+y=(1/8)tangent(theta)?

  • anonymous
that's a trig substitution from right angle trig. basically if you have an integral of the form \[\sqrt{b^2+a^2x^2}\]you can make the substitution x = (a/b) tan Θ
anonymous
  • anonymous
I reversed that. x = (b/a) tan Θ

so the x is (3+y), the b is 1 and a is 8? right?
