solve it using secant method "numerical"

use matlabe

this is my solution can you find the error

Q2) According to Archimedes' principle, the buoyancy force is equal to the weight of fluid displaced by the submerged portion of the object. For the frustrum of a cone as depicted in the figure, use the Secant method to determine the height, h1, of the portion that is above water. Employ the following values for your computation: r1=0.5m,r2=1m,h=1m,f= frustrum density =200kg/m3, and w= water density =1000kg/m3. Note that the volume of a frustrum is given by: V=3h(r12+r22+r1r2) FB=wvg=vfgb(hh1)(r12+r22+h1)N=3h(n2+r22+r1v2)fhh1=(r12+r22+r1v2)wh(r12+r22+r1v2)fh1=h(r12+r22+hr2)wh(r12+r22+r1r2)f Commans Window >> unt it led Nak >) untitied Nak 3) untitied fx+
