Evaluate: `intdx/sqrt ((x-1)(x-2))`

Evaluate: intdx/sqrt ((x-1)(2-x))

Evaluate : intdx/sqrt((x-1)(2-x)) by the substitution x=1+sin^2theta . Hence, find the value of int_1^2dx/sqrt((x-1)(2-x))

Evaluate: intdx/sqrt (4-x^2)

Evaluate intdx/sqrt ((x-a)(b-x))

intdx/(xsqrt(x-1))

Evaluate: intdx/sqrt (16-2x-2x^2)

Evaluate: intdx/sqrt (10-8x-2x^2)

Evaluate: intdx/sqrt (4-2x-2x^2)

Evaluate: intdx/sqrt (x^2-3x+2)

Evaluate intdx/sqrt (1-2x-x^2)
