i want numerical answer ! using matlab ! please higliht required answer correctely

Using secant method find the smallest b>0 such that 0bxx+21+2+sinxdx=3. Calculation accuracy =0.0001 (four decimal places after the decimal point). Problem for grade, 10". Answer: Question 4 Flag question Solve the Cauchy problem y+34+x2y+(2+x+cosx)y+(x2+1)y= ln(1+x),y(0)=4,y(0)=2,y(0)=8 on the interval [0,7]. Find y(6.68) accurate to within =0.0001. Question 5 Flag question Solve the Cauchy problem (x2+2x+5)y+(3x2+2+sin4x)y=x2+3x2+x+7,y(4)=5 on the interval [4,8], Find y(5.02) accurate to within =0.0001.
