Homework Statement
Integrate sin^-1(sqrtx)
Homework Equations
The Attempt at a Solution
To solve this, I first made a substitution of u=arcsin(sqrtx) so dx=sqrt(1-u)du
Still pretty difficult to solve, so I integrated by parts with v=sqrt(1-u) dw=udu dv=(1/2)(sqrt(1-u))2 and w=(1/2)(u^2)
To integrate this new equation, I used a table to get this: sqrt(1-u)(1/2)(u^2) + (1/2)arcsinu + c
I put this all together and changed the u to arcsin(sqrtx).
I'm wondering if this was a legit way of solving this equation.
