## Homework Statement

2

∫ dx / (x+1)√[2x(x+2)]

1

## Homework Equations

Let x = tan θ if √(a^2 + x^2)

Where a = constant

## The Attempt at a Solution

2

∫ dx / (x+1)√(2x)√(x+2)

1

2

1/√2 ( ∫ dx / (√x)(x+1)[√(x+2)]

1

Now make all x in terms of √x so we can apply relevant equation ( applied also to constant )

2

1/√2 ( ∫ dx / (√x)((√x)^2+1)[√(√x+2)]

1

Now before i go on I want to ask if this is possible so I can apply the rule of the tangent in substitution?
