Let the function y(x)(x≥0)second-order differentiable,andy(x)>O,y(O)=1,make thetangent line of the curve and the perpendicular line of the X-axis at any point P(x,y)on thecurve y=y(x).The area of the triangle enclosed by the above two lines and the X-axis isdenoted as S1,and the area of the trapezoid of the curved edge with y=y(x)as the curvededge on the interval [0,x]is denoted as S2,and 2S1-S2 is always set as 1,and the curve Yis obtained Is equal to the equation of y(x).yy=y(x)1P(x,y)0X
