Question

another more question...
∫√(1- x²) -1 / √(1- x²) dx
do I need to use substitution method?
but then I got du = -2x dx but there's no such thing to solve it that way...

Answer 1

no

Answer 2

then what should I use?

Answer 3

you can simplify it first

Answer 4

√(1- x²) -1 / √(1- x²) = √(1- x²) / √(1- x²) - 1 / √(1- x²)

Answer 5

1/sqrt(1-x^2) is simply gonna give you the sin inverse

Answer 6

its x-(sin^{-1}x)

Answer 7

right +c of course

Answer 8

yes

Answer 9

simplify it

Answer 10

then the answer should be x - sin^(-1) x +c ? tq so much (:
