Hello I need to fins the numerical solution of the given equation :
I want to find the value of k where the curve cross the x-axis.
attached is the equation .also pplease see my code.
%Numerical solution to determin the value of K
density =7.9 ;%g/cm^3
Ri =0.35;%cm
Ro =0.4;%cmMlaser =1.5;M =64.4+Mlaser;l=9;%cmMt= density*pi*((Ro)^2-(Ri)^2)*l;solvk =@(k)1+cos(k*l)*cosh(k*l)+ (M/Mt)*k*l(cos(k*l)*sinh(k*l))-sin(k*l)*cosh(k*l);k =fzero(solvk,l);
