`int(dx)/(sqrt((2-x)^(2))+1)`

int(dx)/(sqrt(1-x-x^(2)))

int(dx)/(sqrt(a^(2)-x^(2)))=sin^(-1)(x/a)+C

Let x and a stand of distance is int(dx)/(sqrt(a^2-x^2)) = (1)/(alpha)sin ^(-1) (alpha)/(x) dimensionally correcy ?

int(dx)/(sqrt(2x^(2)+x-1))

" 3.(a) "int(dx)/(sqrt((x-2)^(2)+1))

int(dx)/(sqrt((x-1)(x-2)))

int(1)/(sqrt(x-x^(2))) dx

int(dx)/(x-sqrt(x^(2)-1))

int(dx)/(x^(2)sqrt(1-x^(2)))

Evaluate: (i) int(1)/(sqrt(a^(2)-b^(2)x^(2)))dx (ii) int(1)/(sqrt((2-x)^(2)+1))dx
