An integral is the area under a curve f(x) = y = √(1-x²) squaring.. y² = 1 - x² x² + y² = 1² a bell should ring at this point. this is the equation of a circle radius = 1 centered at 0,0. because x² is a 2-to-1 function and the limits are x=0-1, only 1/4 of the area contributes. A = πr²/4 = π/4. So the value of the integral is π/4
