$$\int\limits_{0}^{1} 1 \cdot \frac{1}{\sqrt{- y^{2} + 1}}\, dy$$ 
Integral(1/sqrt(1 - y^2), (y, 0, 1))
Detail solution

    TrigSubstitutionRule(theta=_theta, func=sin(_theta), rewritten=1, substep=ConstantRule(constant=1, context=1, symbol=_theta), restriction=(y > -1) & (y < 1), context=1/sqrt(1 - y**2), symbol=y)

  1. Now simplify:

  2. Add the constant of integration:

The answer is:
