Stupid question but. I am doing arc length formula but I don't know how they simplified.
How do you simplify Integral of sqrt [[e^(2x) -2 +e^(-2x)]/4) +1]
the solution is 1/2 integral sqrt(e^2x+2+e^-2x)
Why did it go from -2 to + 2 inside the sqrt after they took the 1/2 out?
and for the +1 you can just take outside because sqrt 1 = 1?
